Picking a new strap for a GMT watch is generally good fun. Reason? Because GMT watches almost always have a splash of colour, and that element is probably the principal reason you bought the watch. GMT fourth hands tend to be a different colour from the rest of the watch, giving you the perfect excuse to experiment with different strap colours. If you have, for example, a GMT Master II with a green second time zone hand, then a dark military nylon with a single green stripe looks superb.
Arguably, the GMT of the year is the Tudor Black Bay with the Opaline dial, Pepsi-style bezel and red GMT hand. The embarrassment of riches of colour in this watch makes it an excellent watch head for a bit of strap hunting.
Though not connected to the Space Race, the Tudor GMT's specific colouring and this very robust hook and loop strap are perfectly matched.
As you would expect, ZULUDIVER has not compromised on quality, with the strap being made from high-strength slanted nylon made by a unique shuttleless weaving process that offers superior friction resistance and colour retention. The military-grade non-fray hook and loop fastening system is hypoallergenic and will work in temperatures as low as -30 degrees. It should securely open and close more than 5,000 times. The matt, corrosion-resistant steel loop is embossed with the ZULUDIVER logo.
High-quality rubber straps work well on any tool watch because they bring comfort and smartness. If the Tudor GMT is fit to accompany you to any country regardless of weather conditions, rubber makes a superior strap choice to match this traveller's watch. Taking inspiration from 1960s Seiko waffle straps, the Seacroft FKM is a thoroughly modern design made without compromise. It is technically one of our most advanced diver straps with robust characteristics, making it ideal for any watch which lives in challenging climates.
The scientific name of FKM is Fluoro-Elastomer. It is a tough wearing rubber compound highly resistant to salt water, aggressive chemicals, and extreme temperatures (as low as -45C and as high as +300C). That should definitely cover you for anywhere on the Planet.
Grey is a versatile colour to offset against tool watches and sits nicely against the Tudor's case and, surprisingly, the dial. This premium strap has a subtle ribbed texture to the nylon, similar to old-fashioned military webbing. The 1.2mm thick nylon is incredibly tough and hardwearing.
The buckle and keepers are fashioned from stainless steel, and the keeper nearest the buckle is floating so that you can adjust it to suit the excess nylon you have. With a length of 285mm, this strap will fit any wrist size from 6 inches to 9 inches (15.25cm to 22.86cm).
Leather 1973 straps bring an old-school military and adventure look to any watch. They soften and patina with age and could be the perfect partner for a traveller's GMT. Just take a moment to look at the watches we have used as photo models for this strap, and you will see the imagery it creates: Tudor, Rolex, Citizen' Ray Mears'.
This strap is cut and crafted from oiled 'crazy horse' pull-up natural premium leather. Over time, 'crazy horse' leather will absorb the natural oils from your skin and cause the leather to form a glossy sheen that will make the watch strap look even better. It has been carefully stitched with strong coloured thread fitted with a classic style stainless-steel buckle.
We also have a detailed strap with a hot-stamp line around the edge, and hand-painted and sealed the edges with coloured stain. This strap is available in three fitting sizes: 18mm, 20mm or 22mm.
The Opaline dial of the Tudor is begging for the boldness of a white strap, and what better choice for the ethos of this watch than durable FKM rubber?
Our Vintage Tropical strap is inspired by the golden age of diving watches in the 1960s and pays homage to tropical straps from a bygone era. It has a generous tapered tail, classic style keepers, and a period-accurate textured pattern. Yet this thoroughly modern strap is made from hi-tec FKM rubber and has quick-release spring bars.
The smaller perforated vents are carefully designed to allow airflow through to your skin, water to drain and for significantly greater user comfort in hot climates. It's an outstanding match for a global adventure watch like the Black Bay GMT.
It is time to bring out one of the colours on the Tudor GMT – the red of the Pepsi bezel. The Mayday Anchor Divers Sailcloth strap is in a striking new design for 2023. With a coloured backing and perforations in ascending and descending sizes, it brings classic style and functionality.
This strap is waterproof, just like your Tudor and lined with vegan-friendly Lorica for an unbeatable combination of durability and comfort. Our Sailcloth is made up of three layers, which combine to create a superior strap. The first layer provides comfort against the skin. The next layer, a grey neoprene foam, offers a flexible element that stands the test of temperature and time. Finally, the top layer flaunts black PVC rubber adorned with an embossed sailcloth pattern, a mark of rugged style and robust, abrasion-resistant finesse.
Have we left the best till the last? A strap specifically made for watches with a 'Pepsi' dial. Our Simple Handmade Italian Leather Strap offers timeless simplicity, making it a popular choice for anyone after a quality leather strap. With a 4mm to 3.5mm tapering thickness, the Italian leather can withstand a great deal of wear whilst still being pliable from the outset, and it conforms well to the wrist.
The blue and red accent stitching has been crafted to enhance your GMT watch, showing our respect and affection for the venerable Pepsi bezel. The strap also comes equipped with quick-release spring bars for easy strap changes and a stainless steel buckle etched with the WatchGecko logo for reassurance of a genuine quality product.
So there you have seven excellent strap suggestions for your Tudor Black Bay GMT or any GMT watch you own. The fact that we can easily pick seven straps, and there are so many more we could have selected, shows the outstanding versatility of the Tudor.
