Hi guys, I've searched for a definitive answer to this, but still can't find one. Are there two different sizes or spring bar, depending on strap or bracelet, to suit the Seamaster 300? I went to an Omega Boutique last week to get a Nato strap. They came back with my watch (Nato fitted), the original bracelet and two spring bars (I assumed the original ones from the bracelet) in a plastic bag. I assumed that they just put new spring bars on, because I had asked about this beforehand, but didn't think much of it. Fast forward until today and I went to swap NATO for the bracelet for a change, using the two spring bars in the bag. Could not for the life of me, get the spring bars in. Tried the bars by themselves (without the bracelet to get in the way) and I could JUST squeeze them in, but can't imagine it's possible on the bracelet. I then noticed that the bars that were with the NATO were slightly shorter. (23.42mm uncompressed V 24.41mm). Put the shorter ones in the bracelet and fitted it no problem. I did some searching and found this; Hoping someone can clarify this once and for all, are there different sizes for bracelet or strap? Thank you kindly.
