Leather NATO G10 Straps
I can supply to special order leather NATO G10 style alternatives to nylon NATO G10 straps for military watches. These are made in the leather colour of your choice, are much more stylish and comfortable to wear than a nylon strap, and I also think they look more "period" on an older military watch.
NB: My leather NATO G10 style straps are not exact copies of the nylon service straps for several reasons, so please make sure you read all the information here so that you know exactly what you are getting. I don't keep NATO G10 straps in stock because the number of permutations of hardware, width and leather colour are too many for me to hold stock of all of them, so each strap is custom made to your order. This has the benefit that it can be made to fit your wrist size, but it can take up to two to three weeks to get it made.
If you have any questions, plese feel free to email me at Please don't give out my email address, refer anyone interested to this web site. I try to answer all emails I receive so if you don't get a reply in a few days please check your junk or spam folders.
My Standard Design and Mark II Design
When I first asked the workshop to make some leather NATO G10 straps, I thought that they would just make faithful copies of the service nylon versions, just shorter. But the workshop realised that the standard design of the NATO G10 strap puts the watch head close to the buckle, meaning that the buckle sits on the side of the wrist rather than underneath it, so they moved the position of the keepers to make the strap more wearable. However, this does mean that the keeper positions even on my "standard" G10 design are not an exact replica of a service G10 strap.
After some customer comments about my standard G10 strap positioning of the buckle on the side of the wrist being uncomfortable I designed a revised "Mark II" design that looks like the standard NATO G10 but places the watch head further down the strap so that the buckle sits under the wrist rather than to the side. I find these are much more comfortable to wear than the standard G10 design.
The difference between my standard and Mk. II designs is explained in more detail below.
Defence Standard (DefStan) 66-47
The basic design of the NATO G10 strap, as shown in the drawing from Defence Standard (DefStan) 66-47, calls for the positions of the metal loops to be increments of 12mm plus 25mm plus 60mm from the buckle end of the strap. This means that that the watch head is held very close to the buckle. This design means that if you wear the strap what I would call the "normal" way, that is with the buckle at the top, so that the buckle passes over your wrist and the tail of the strap passes under your wrist as you put the strap on, the buckle sits on the outside of your wrist rather than underneath it. It may be OK if you are used to it from wearing a service issue nylon strap, but I find this position of the buckle to be uncomfortable.
Drawing from Defence Standard 66-47
Reading from the top: 1: G10 nylon. 2: My Standard G10 leather design.
3: One of my Type B straps. 4: My Mark II leather G10 design.
You can see why the standard G10 buckle sits where it does by referring to the picture on the right. The top two straps are a nylon G10 and one of my leather G10s. However, these two straps are not made exactly to the DefStan specification, the position of the loops has been moved a little so that the watch head can be placed further away from the buckle, although you would be hard pressed to tell without actually measuring it.
You can see how closely the leather G10 matches the nylon - it is just made shorter to suit the individual's wrist - mine in this case - because a large excess of leather is much harder to tuck away than nylon. However, even with this modified "standard" design I still find that the watch head is held too close to the buckle for comfort.
The third strap in the picture is one of my Type B vintage straps, and you can see how much further down the strap the watch head sits. When I wear this strap the buckle sits undeneath my wrist, which is the usual place and where I find it comfortable. My revised "Mark II" design of the G10 looks as much as possible like the standard NATO G10 and uses the same hardware, it but places the watch head further down the strap so that the buckle sits under the wrist rather than to the side. I find this much more comfortable to wear than the standard G10.
Both of my "Standard" and "Mark II" G10 NATO designs can be supplied with either standard or ZULU harware. You will find separate ordering buttons for the two designs below.
Leather NATO G10
standard hardware, cognac
My standard NATO G10 Leather Straps have traditional polished stainless steel fittings, which are shown in the picture to the right here, and also in the picture of the four straps above. Standard hardware can be made up into straps of my standard design or my Mk. II design.
Standard stainless steel hardware is available in widths from 12mm to 24mm in increments of 2mm. Gold coloured standard hardware is available in 18 or 20mm - if you want gold coloured hardware please select the 18 or 20mm option and then let me know that you want it in gold colour.
I don't keep these in stock but you can place an order for one to be made for you using the buttons below.

ZULU hardware, black
The ZULU hardware has a round cross section and is heavier than the standard NATO G10 hardware. My understanding is that the ZULU hardware was designed to be stronger than the standard hardware for dive purposes as opposed to aviation. I think the two rings the end of the short strap are be for extra security. ZULU hardware can be made up into straps of my standard design or my Mk. II design.
ZULU hardware is available in 18mm, 20mm, 22m or 24mm widths in bright stainless steel only. Because of the extra cost of the ZULU hardware, straps with ZULU hardware are slightly more expensive at £27.50.
Again, I don't keep these in stock but you can place an order for one to be made for you using the buttons below.
Construction, Thickness and Length
The standard NATO G10 nylon straps are made extremely long, not only to accommodate different size wrists but also to be worn on the outside of clothing. The long tail is usually folded back and tucked under one of the keepers. With a leather strap this presents a problem. A leather strap the same thickness as a nylon strap would be very weak. You will see straps like this advertised as being "soft" and "flexible", which is true, but for some reason they don't also say that they are "floppy" and "weak".
I prefer to supply leather straps that will last, so my straps are made in the traditional way, from two pieces of leather glued back to back and stitched all round. The finished thickness is about 2mm. A strap of this thickness can't be folded back on itself and tucked under a keeper like a nylon strap, so my straps are made shorter, without the long tail of the nylon strap. This means that the second keeper ring is not needed to tuck the long end of the strap into, although we make the strap up with it in place for authenticity.
Stitching all the way round obviously involves a cost, but it means that the two pieces of leather aren't going to come apart after a little bit of wear as can happen with cheap copies that are simply glued. Unstitched straps also stretch easily in wear. I have in the past, against my better judgement, supplied straps made from a single thickness of leather, and straps made from two thicknesses but unstitched, but due to customer dissatisfaction with these I will not supply any more - as an engineer by training and at heart, I prefer things made in a way that I feel comfortable with.
From experience the standard length of my straps suits most people, but how this fits your watch and your wrist does depend on how chunky your watch is, because of the way the strap loops through the lugs, and how tight you like to wear your strap. If your wrist is measures less than 165mm / 6½" around, or more than 195mm / 7&2/3" around, or your watch needs the strap to take a more than usually convoluted path so that more than usual of the strap is used in attaching the watch, please send me a measurement round your wrist and / or a picture of the lugs of your watch, and I'll adjust the strap length to suit you.
The most reliable way to measure your wrist is to wrap a dressmaker's tape measure around your wist at the point you wear you watch and take a reading from this, or wrap a piece of string around your wrist and make a mark with a pen where it overlaps and then measure the distance between the two marks with a rule. If you take a measurement from an existing strap this produces a slightly different result, so please make sure to let me know if this is what you have done.
Strap / Band Width
I can only supply straps in even sizes, that is even numbers of millimetres i.e. 16mm, 18mm, 20mm etc. which is determined by the cutters in the workshop. If you are sure that your lugs are an odd size, I always advise that you go for the next larger size, e.g if you measure your lugs as 17mm, get an 18mm strap. It will fit with a bit of careful threading through: leather is a marvellous material which will squash down to fit the lugs. This looks a lot better than a narrow strap that leaves your watch slopping about from side to side. And also leather straps always get slightly narrower as you wear them, because as they stretch slightly in length, they contract in width, and you don't want it to go sloppy after a few wears.
The ordering buttons below have options for the most popular colours, but if you want a strap in a colour not listed, then please send me an email. I can supply dark green, red, yellow, blue, white etc. as well as metallics - probably not usual for a G10, but then what do I know - you're the customer! I have supplied a NATO G10 in white and it looked rather nice.
Cognac / Chestnut We have now run out of cognac leather and can't get any more (see leather if you want to read more about my constant struggles to find suitable leather) so any straps order to be made from now on will be in a new version of chestnut. Some of you may remember the old chestnut that preceded the cognac; this version is a little lighter and "brighter" than the old chestnut and the cognac. I have put a picture of the chestnut on the pictures page.
My leather G10 straps are made in the same way as my replica Great War / WW1 period vintage straps, so please refer to the page that describes them for the full details: Construction Details.
One feature that I get asked about is contrast stitching, which can be done, see Contrast stitching for details.

Please note that I don't keep leather NATO G10 straps in stock, there are far too many possible variants of width and colour, so your order will be made specially for you. Because of this, please allow two to three weeks for manufacture before dispatch.
Because these straps are custom made to your order, they can be made to any length to fit your wrist. Just let me know if your wrist measures more than 7½" / 190mm or less than 6½" / 165mm around and I'll adjust the length to fit you.
These leather straps don't have the very long tail of the nylon strap and so the second keeper ring is not needed to tuck the long end of the strap into, although we make the strap up with it in place for authenticity.
Leather will harden and crack if subjected to repeated soaking in water and therefore leather straps are not suitable for swimming or diving.
Postage / Shipping
I am based in Cheshire, England, but I am happy to take orders from anywhere in the world, and I have many satisfied overseas customers. You can pay securely on line by PayPal using your credit or debit card, even if you don't have a PayPal account. I can take payment in any currency, dollars, yen, whatever you like, PayPal handles the currency conversion. Just simply follow the instructions and you will be charged in your preferred currency.
Postage in the UK is by Royal Mail First Class. Overseas shipping is by airmail, which takes a few days to Europe, up to 10 days to destinations out side Europe, but can take longer if delayed by your incoming Customs Authorities so please take this as just a guide. Shipping time to the USA by Royal Mail airmail is usually overnight from Manchester to JFK and delivery on the East Coast is then usually a few days, but occasionally delays by US Customs and US Postal Service can cause delivery to be 10 days to two weeks, sometimes even more to the West Coast.
Please don't forget to buy postage & packing / packing & shipping for your region. This is something that PayPal buttons can't work out, so I have included the postage options as separate buttons.
