Require Ref# for IWC Pilot Chronograph 3717 Allogator Strap please

Seasons greetings ladies and gentlemen,

I was hoping for some advice please to point me in the right direction. I wish to order an IWC Allogator strap, black, 21mm (18mm buckle end) fit for OEM buckle.

I would like the one that was sold new with most standard IWC 3717 Pilot watches.

I received a reference number from an Authorised Dealer yet have a suspicion, after performing a web-search, it may be incorrect. I was given IWA59207; however photos of a different strap appears when searching; www.kronopassion.com/IWCpilotstrapcroc3.JPG (not what I am after).

The strap in question I am after;

Hi,
I think as you have found that the strap number you were given is for the latest 3777 Pilot.
The 3717 strap number, black, std length for pin buckle is IWA19247 but please do check this first.

Hello and thanks for the reply.

This does make sense. I will go and confirm with our states only IWC dealer and confirm the salesman did not make a mistake.
