20mm Soft Rubber Watch Band Compatible with Many Citizen Aqualand Promaster Diver Watches (Depth Measurement ND Limit Printed in FEET)

The band must be taking Ozempic, the skinniest or narrowest dive band I have ever had.

Material is silicone rubber. Yes, it is softer than polyurethane but the tip of the strap is very hard to insert into the two little sliding keepers that are meant to hold the strap in place. I struggled to get the strap into the keepers because the openings are narrow and the silicone surfaces don't slide easily across each other. All the real polyurethane straps I've had on my many dive watches are easy to insert into the buckle and keepers. I bought this only because the description plainly says "Polyurethane." It isn't.
