Fit guide
Which rubber strap fits your Omega Seamaster?
The Diver 300M and the Aqua Terra 41 have 20 mm between the lugs, the Planet Ocean 43.5 has 21 mm. Our fitted FKM rubber strap is moulded for the Diver 300M of 2018 on (42 mm) and sits flush with no gap; for the other Seamasters, pick one of our leather straps with straight ends in the right width.
Questions buyers ask
What strap size does an Omega Seamaster take?
20 mm between the lugs for the Diver 300M (42 mm) and the Aqua Terra 41, 21 mm for the Planet Ocean 43.5. The reference is on the warranty card, or search it in the finder above.
Which Seamaster does the fitted rubber strap fit?
The Seamaster Diver 300M of 2018 on, 42 mm, with the wave dial (references 210.30.42.20… and 210.32.42.20…). It is not made for the older 41 mm Diver, the Aqua Terra or the Planet Ocean, whose cases are shaped differently.
How do I change the strap on a Seamaster?
The spring bars sit between the lugs: push each one in with a spring-bar tool, lift the strap out, and fit ours the same way until you hear the bars click in. Masking tape on the lugs protects the polished case.
Is FKM rubber better than silicone?
FKM (fluoroelastomer) is denser than silicone: it does not attract dust, keeps its colour and stays soft without turning sticky, which is why it is the rubber used on premium watch straps.
Is it good for swimming and diving?
Yes. FKM does not mind salt water, chlorine or sun: rinse it in fresh water after the sea or the pool and let it dry. The butterfly clasp is stainless steel.
