Strap for GMT-Master II Yellow Gold SA

The Rolex GMT-Master 116758 SA has a lug width of 20mm. This measurement is determined by the space between the case lugs and is essential for selecting the correct strap. Precise measurement ensures proper fitting without lateral play and maintains the original aesthetic.

For the 116758 SA in yellow gold, we recommend authentic alligator for formal elegance, vegetable-tanned calf for those who appreciate natural patina, or shell cordovan for daily versatility with superior resistance. Rubber remains a practical alternative during warm months when gold tends to heat the wrist.

The change requires opening the case with appropriate tools to access the mounting pins. The pins must be extracted horizontally with a small lever, the old strap removed, and the new one inserted whilst aligning the holes. It is recommended to entrust the operation to a qualified watchmaker to avoid damaging the case or pins.

Yes, any strap with a 20mm lug width is compatible. However, construction quality influences durability and comfort. Artisan leather straps maintain the watch's aesthetic value and develop patina over time, whilst budget options tend to deteriorate rapidly.

A strap made from quality leather and vegetable tanning has a lifespan of 3-5 years with daily use, extendable to 8-10 years with proper care: gentle cleaning with a damp cloth, air drying, and occasional application of specific balm. Environmental factors such as humidity, temperature, and sun exposure accelerate wear.
