Strap for Diver Quartz GMT Black / Calf

The Formex Diver 2100.3.2022.213 features a lug width of 22mm. This dimension was chosen by Formex to maintain precise proportions with the 46.50mm case diameter. When measuring the lug width, verify the actual width of the attachment pins rather than the space between the case lugs.

For the Formex Diver 2100.3.2022.213, we recommend vegetable-tanned alligator straps for a sober and sophisticated aesthetic, vegetable-tanned calf leather for soft hand-feel and evolved patina, or vulcanised rubber for complete water resistance and technical functionality. Choice depends on intended use: professional environments benefit from natural leather, whilst nautical or outdoor applications favour rubber.

Strap replacement is performed by removing the spring bars that retain the strap to the case lugs. Equip yourself with a spring bar remover tool, insert the flat tip into the pin aperture, push gently outward to release the spring, and slide the pin out of the lug. Reverse the procedure with the new strap, ensuring the pins tilt slightly downward before full insertion.

Yes, provided the strap is manufactured with precise tolerances of 22mm ±0.3mm. The lugs on the 2100.3.2022.213 feature a subtle chamfer on the edges, so straps with very tight tolerances may snag during insertion. Artisanal quality straps respect this standard and ensure smooth yet stable fit.

Leather strap durability depends on tanning method, usage and maintenance. Vegetable-tanned calf typically lasts 3-5 years with daily wear and regular cleaning. Vegetable-tanned alligator is more resilient and may exceed 7-10 years if properly maintained. Prolonged sun and humidity exposure shortens lifespan. Occasionally applying a neutralising balm and allowing leather to air-dry naturally extends longevity considerably.
