Strap for Submariner Date White Gold / Blue

The lug width of the Rolex Submariner 116619LB is 20mm. This measurement is determined by the case geometry and represents the distance between the centres of the attachment holes. Any aftermarket strap must have a width of exactly 20mm to ensure correct mechanical compatibility without lateral gaps or insertion impediment.

Alligator is the historical and ideal aesthetic choice for the 116619LB: the natural grain of the leather captures light similarly to brushed gold, creating visual continuity. Vegetable tanning develops an ageing patina visible within 6-12 months, accompanying the white gold's chromatic journey. Shell cordovan is an excellent alternative for daily non-diving wear, offering outstanding depth and resilience.

The 116619LB uses standard Oyster lugs with a spring bar (not an original deployante, although aftermarket 20mm deployante versions are compatible). To change the strap: remove the spring bar with a proper tool, extract the old strap and insert the new one into the lug seat ensuring the width is exactly 20mm. Balanced pressure on both sides facilitates spring bar insertion.

Yes, any strap with a 20mm lug width is mechanically compatible with the 116619LB. The recommendation is to choose manufacturers that guarantee structural rigidity of the lug seat, as the strap must tolerate lateral pressure without permanent deformation. Avoid fragile constructions or insufficiently treated leathers.

A high-quality leather strap (alligator, shell cordovan) lasts 18-36 months with daily use and minimal maintenance (occasional cleaning, protection from excessive moisture). Vegetable tanning ages visibly but remains functional beyond 5 years. Perspiration, salt water and constant UV exposure reduce durability. Casati Milano guarantees 18 months against manufacturing defects and offers regeneration services.
