Reference number for 168.1623 rubber strap

Hello All,

I recently purchased a 168.1623 Seamaster and have been investigating a genuine navy rubber strap to pair with it. I’ve found the strap with reference 98000210 from that era which is pretty nice, but from some other conversations I’ve had I heard there was a articulated lug rubber strap with a tang clasp that was made for this reference as well. Apparently it’s quite rare and doesn’t come up for sale that often. No one knew the reference number but I was wondering if anyone in the forum might have some more information.

thanks in advance!

Perhaps you mean ref. 97988082?
