Strap for Seamaster Planet Ocean 600M Co-Axial 42 Mécanique 18 Sapphires / Short Strap

The 2914.50.48 model features a lug width of 20mm. This dimension, also called lug width, is the distance between the two case lugs. Verify the measurement with a digital caliper: the lugs must be exactly 20mm apart for a compatible strap with no lateral play.

The choice depends on use and personal style. For sporty-formal elegance, we recommend alligator in cognac or dark brown tones, or shell cordovan that develops a patina over time. For daily wear with a more technical register, vegetable-tanned calf leather in black or navy blue, or vulcanized rubber strap with Cordura fabric. The 20mm lug width is compatible with all these options.

You will need a spring bar tool. Position the watch on a soft surface, locate the lower lug pin of the strap you wish to remove. Insert the flat blade of the tool into the small groove, gently push inward to release the spring pin, then extract it laterally. Repeat for the opposite side. Insert the new strap, ensuring both pins are correctly positioned and locked.

Yes, provided it features a lug width of 20mm. Milanostraps offers hundreds of compatible straps in leather, fabric, and rubber, customizable in size. Always verify that the strap is suitable for sports diving watches, with robust lugs and a buckle (or deployant clasp) that supports the weight of the two-tone case.

A premium leather strap (alligator, shell cordovan, calf leather) on a watch with 600m water resistance has an average lifespan of 2-3 years with normal daily use, increasing to 5-7 years if worn occasionally. The case water resistance does not mean the strap tolerates immersion: for swimming and water activities, mount a rubber strap. Periodic maintenance (gentle cleaning, protection from excessive humidity) significantly extends longevity.
