33.3mm. It is very thin though at 6.75mm. The other downside (imho) is the 215 movement. It seems that it is (still, I believe) PP's catch-all movement they put in a lot of watches.
If it was a good price and I had a small wrist I might be tempted, but I would prefer the 240 movement until PP decides to make a new manual to fit modern sizes (38-40mm).
Good luck.
