Torn on the Speedmaster cal 3861

I’ve owned previous Speedmaster cal 1861 watches. I currently own the newer cal 3861. I love everything about the watch. I feel they got the bracelet right, the subtle refinements to the dial, and the chronometer and Meta certification is a nice plus. I’m just trying to understand the whole co-axial escapement change. I was a little disappointed that they would touch the heritage of the Speedmaster. I’m hoping there must be some benefit, Rolex has introduced their new escapement called the dynapulse. I know the coaxial escapement doesn’t add to longer servicing intervals but my understanding is that it improves consistency through the servicing interval of the watch. If it’s for nothing more than brand inclusiveness than I guess that bothers me, although I know this exists in all luxury items. I didn’t buy this watch as a luxury purchase but because I appreciate the horological history and I like tool watches. Adding a coaxial escapement for brand inclusiveness with no real benefit somewhat cheapens it for me. If that’s the case the previous 861/1861 feel more honest because they didn’t need that inclusiveness as they already had it being the history of the watch. It there is real world benefits please let me know your thoughts.

IMHO the heritage continues from c.321 to c.861 to c.1861 to c.3861. Enjoy them all!

I think this is the right answer. "(1)861" feels more honest" misses the point when the movement that gave the Speedmaster the "moonwatch" moniker was the 321. I think it's a natural evolution of a great watch.

The 3861 is more accurate, has more power reserve, is anti magnetic,…

Whether it’s due to the escapement or not, it brings real world benefits over the 1861 so what’s not to like?
