Strap size for IWC Pilot Chrono Le Petite Prince. IWC 377714

Not sure if this question has been asked in the past but i am new to this
forum. So on the specifications of strap size IWC website indicates 21mm as
the size of the strap for this particular model. However when i measure the
log width its only 20mm and the santoni strap that came with the watch
measures 20mm. Any thoughts on this descrepancy?? The 20mm seems already
pretty tight I can't imagine trying to get a 21mm on it. The reason I am
asking is because I planning to purchase an after market strap and i need to
know what size to get. Thank you in advance for any constructive responses.

I would trust the technical information provided by IWC. The 3777 is supplied
with a 21mm strap (or bracelet). You might find a 20mm strap that works
but over time it may loosen up and become too loose. If you are looking to
purchase a new IWC strap, I would recommend you stick with 21mm for that
watch.

Thanks Ben, greatly appreciated the reply.
