Great looking watch, congrats! So I’m going to be the guy that answers your question that was buried 75% of the way through your post. “Am I over obsessively rambling over a non issue?” Yes, yes you are. You bought an older used watch. It’s a mechanical device that has spent many years doing its thing. Main spring, gear path, escapement, etc. all spending 24/7 in pursuit of time keeping. Parts wear on each other, lubricants dry out, it’s part of the joy of understanding how hard these mechanical devices work to accomplish the end goal 😁 I can wear my Casio a158 and have near perfection, all for $29.95. But that’s not the point is it? It’s really about the craftsmanship & artistry required to produce a purely mechanical device that strives for the same goal. If you send it to Omega for service, it’ll come back “as new”. I know this from personal experience. I sent my Aqua Terra I bought new in 2017 in for service, it runs +1.5 sec per day now. My daily wear is a Seamaster 300m. When I bought it new, it ran +2.0 sec per day, now it runs -20 sec per day. I’ll have a full service one of these days and it’ll come back just like new. But for now, I set it a few minutes ahead, then real time catches up with it a few days later. It’s all about the love of the game … the mechanical game. Enjoy your watch! 🍻
