I have a larger size wrist at 8.5 inches. Most of the rubber straps I see advertised won’t fit me. Is there any good rubber straps in bigger sizes?

 

Isofrane may be an option as the holes on the 6 o'clock side go quite far to the end. They also have dive extensions for the strap. But they are purpose built for diving so the look may not work for all watches.

 

Thanks. These may work good. They would be on a Seamaster 300.

 

Rubber B’s cuff line purports to accommodate up to a 9” wrist

They also now offer a rubber NATO

The site doesn’t describe the length of these NATOs, but perhaps contacting their customer service would clarify

pretty interesting, a rubber nato …

 

i bought one for my panerai from etsy!
