5004 Big Pilot Strap Question

I need to know the "regular or standard" strap lengths (short end & long end)
for a 5004 Big Pilot, with a deployant clasp. Your help will be greatly appreciated.

There are 3 sizes:
135mm x 55mm
145mm x 55mm
155mm x 55mm

Isn't there a XXS strap also? Thought there was a recent post showing it side by side wit the shorter short section.

yes, in the post I referred to earlier.

Thanks everyone for the information. I now know that I need a "Small"
for my 7 3/8" wrist.

Lowell, you can't think like normal straps here. I have a 7 inch wrist and wear a medium on my 5002.
