Submariner 16610LV MK1— lug 20mm

The lug width of the Rolex Submariner 16610LV MK1 is exactly 20mm, measured internally between the two case horns. This measurement should be taken using a digital calliper placed directly against the metal, not across the outer edges of the lugs. This is the correct dimension to specify when ordering a compatible aftermarket strap.

The ideal choice depends on the intended context. For a casual-sport register, vegetable-tanned calf leather in moss green, navy or black offers the most versatile pairing. For formal occasions, black or anthracite gloss alligator elevates the watch without compromising its character. Shell cordovan in burgundy or dark brown develops a unique patina over time and suits those seeking a more personal aesthetic. For aquatic or intensive sporting use, vulcanised rubber ensures durability and hygiene.

Removing the bracelet or strap requires a spring bar tool with a fine tip. The spring bars are inserted through the lateral holes in the lugs: pressing the tip against the spring bar shaft compresses the spring and releases the end from the hole. Work carefully to avoid scratching the case, using a watchmaker's pad to protect all surfaces. The replacement 20mm strap is fitted by reversing the procedure, ensuring both spring bars click securely into their respective holes.

Yes. The 20mm aftermarket strap market is one of the most extensive in watchmaking. Handcrafted straps from ateliers such as Casati Milano are made specifically to match the curved lug geometry of the Submariner, with pre-formed or flexible ends that ensure a precise fit against the caseback. It is essential to confirm that the strap is made for curved-end cases to prevent any play or mechanical stress at the attachment points.

Longevity depends on the material, frequency of use and maintenance. A quality calf leather strap, worn daily under moderate conditions and kept away from water, typically lasts 18 to 24 months before the inner fibres begin to deteriorate. Shell cordovan, owing to its dense fibre structure, can exceed 3 to 4 years under equivalent use. Alligator, when treated with neutral conditioners and protected from prolonged exposure to perspiration and moisture, can remain structurally sound for several years. Casati Milano provides an 18-month guarantee against manufacturing defects on all handcrafted straps.
