Strap for Seamaster PloProf Co-Axial Master Chronometer Titanium / White / Blue

The lug width is 24mm. This measurement is mandatory: any compatible strap must have an internal width between the lugs of 24 millimeters to fit the forged titanium lugs of the PloProf. Always verify with a digital caliper before purchasing an aftermarket strap.

For this technical-military timepiece we recommend American alligator (fine grain, flexibility underwater) or FKM rubber in saline environments. If you prefer leather, vegetable-tanned calf absorbs moisture without swelling. We advise against decorative straps or ornamental buckles: the PloProf demands constructive sobriety.

The lug pins on the PloProf are fixed and not removable by simple pressure. We recommend entrusting the operation to a certified watchmaker or contacting Omega Service directly for warranty replacement. If you desire a bespoke strap, Casati Milano atelier offers appointment-based service with full customization and 18-month warranty.

No, because the PloProf 22790552104001 features solid titanium lugs with specific 24mm geometry. Seamaster Ocean Planet or Diver 300M often use 20mm or 22mm. Using an incompatible strap creates mechanical play and risk of losing the buckle underwater. Always verify the reference before purchasing.

An alligator or calf strap, worn regularly in underwater environments, typically lasts 18–24 months before requiring replacement. Exposure to fresh water, salt water, and temperature variations accelerate the natural wear of leather. FKM rubber straps last 3–5 years. Casati Milano atelier guarantees 18 months on all bespoke straps commissioned.
