Strap for Seamaster Diver 300M Automatic 36.25 Stainless Steel / Yellow Gold / White / Bracelet

The lug width is 20 millimetres. This is the specific standard for the Seamaster Diver compact models from the 1990s. You can verify this by measuring the distance between the spring bar pins on the case lugs with a digital calliper. Any strap marked as compatible with 20mm lug width will fit perfectly without any play.

It depends on your usage: vegetable-tanned alligator in dark brown enhances the two-tone gold-steel with formal elegance; shell cordovan introduces a patina that evolves over time; calf leather offers chromatic versatility; slate blue NATO amplifies the visual suspension of the case; FKM rubber represents the ideal choice for authentic diving.

Position the watch on a soft surface. Using a spring bar tool, insert the tip into the small hole beneath the upper lug, pushing upward to release the spring. Repeat for the lower lug. Remove the strap, insert the new spring bars into the ends of the new strap (if not already present) and carefully reinsert into the case slots until the spring snaps into place.

Yes. All straps specifically indicated as compatible with 20mm lug width will fit correctly into the lugs of the Seamaster Diver 300M 2352.20.00. Omega's precision engineering guarantees absolute dimensional conformity. Make sure the strap is specified for 20mm lugs and do not confuse it with different standards such as 19mm or 21mm.

An alligator strap with vegetable tanning, subjected to periodic maintenance (cleaning with a damp cloth, conditioning with natural wax every 6–12 months), maintains structural integrity for 4–7 years of daily use. Shell cordovan, thanks to its natural oleo-protective properties, extends this interval to 6–10 years. FKM rubber resists 8–12 years without significant aesthetic degradation. Quality polyamide NATO easily surpasses 10 years.
