Strap for Submariner Date 41 Stainless Steel / Yellow Gold / Blue

The Rolex Submariner 126613LB-0002 features a lug width of 21 mm. This measurement is specific to the two-tone yellow gold and steel variant in 41 mm and is larger than the 20 mm lug width of previous Submariner models. The measurement must be taken perpendicular to the inside of the lug, disregarding any curves or angles of the case.

For the Submariner 126613LB-0002, noble leather options such as vegetable-tanned alligator in dark brown or biological black tones, shell cordovan with natural patina, or full-grain martelled calf are recommended. Alligator is the ideal luxury choice: the grain texture dialogues with the brushed steel finishes and develops a narrative patina over time. NATO straps are discouraged for this model to avoid stylistic incoherence.

The Submariner 126613LB-0002 strap is changed using a spring bar removal tool. Position the flat end of the tool inside the lug of the case, gently push to compress the internal spring of the pin, and extract the pin from the groove. Repeat on the other side. Insert the new pins by aligning the 21 mm strap with the guide holes of the lug.

Yes, any strap with a 21 mm lug width is compatible with the Submariner 126613LB-0002. It is essential to verify the width in millimetres with precision, as construction tolerances are minimal. Artisanal-quality straps, such as those from Casati Milano, guarantee precise compatibility and noble materials superior to OEM Rolex straps.

A high-quality noble leather strap (vegetable-tanned alligator, shell cordovan, full-grain martelled calf) for the Submariner 126613LB-0002 has a lifespan of 3-5 years of daily wear, depending on exposure to external agents (sun, water, perspiration) and maintenance. Vegetable tanning develops a protective patina over time, increasing longevity. Casati Milano guarantees 18 months against defects in artisanal manufacturing.
