Speedmaster Moonwatch - Rubber Straps

Hi all,

Looking for some recommendations for a curved/fitted rubber strap for my 1861 Moonwatch please! Just a simple black with brushed pin and buckle would be great.

Thanks

Zealande do one though they state it's for the 3861. Might be worth dropping them a message to see if it'll fit.
