Speedmaster 145.022 crown sizing

bcousin1 · Jan 10, 2022

Can anyone tell me if I have the incorrect crown and/or stem length on the Speedmaster 145.022 in the pictures? The crown is about 4mm wide and doesn't sit flush against the case. The crown feels wider than another modern day Speedmaster Pro that I've owned and I'm a little concerned about water resistance if the crown isn't fully seated. Could anyone post pictures of there 145.022 so I can compare?

Looks like a Seamaster crown from shape and dimensions. And yes, even though it's from a Seamaster, it won't make your Speedy more watertight 😀

Really, a Seamaster? I'm guessing you mean a modern-day Seamaster 300? From the pictures Sleepyastronaut posted, mine does look slightly wider, but the crown also doesn't look to sit flush against the case. I used to own a Speedy Pro from 2018 and an FOIS, and this crown feels noticeably easier to grip.

I don’t believe it’s the crown itself that determines how close it sits to the case. It’s more likely to be the stem is slightly too long and needs trimming to the correct length.

For your comparison, my Speedmaster Prof. 145.022-69 “220”
