PO +15 again :(
So my PO is about a month old. When I first got it, it was +20-+25. It settled down to a nice +2 - +3 for a couple weeks. I did a test last night and now it's +10 (worn most of the day then sat flat over night). I don't really want to send it in for warranty yet and I guess it's better fast than slow, but,

The Evolution of Longines' Automatic calibers, part 2

This was a much more refined and better decorated (all the bridges were rhodium plated) movement than the predecessor, but you can see some similarities to the 22A. It made sense to take a proven existing caliber from Longines' stable and

Never to buy watch
hi pals, i was kind of bored so...what are the 3 ''Famous'' watches that you doesn't see yourself buying in your life and why? brand and model please.i will start.1- Cartier Must 21: $4,000 for a quartz chronograph, never! and the back is holded by screws, thats a ''no'' for me.2- Bond Seamaster: don't like the skeleton hands, and the scalloped bezel sometimes is difficult to use, i prefer a watch famous for itself not for a movie.3- Invicta Reserve ProDiver: i don't trust the brand, for that price you can get a preloved Tag or a new Orisplease, pals, i have no intension to bash, fight or anything negativeabout those brands, that is my personal opinion.this is for fun.

AP service
I’m considering purchasing an AP. I’m still researching models, but I’m curious about a few things.With my Rolex watches I send them in as needed for service. What is a reasonable timeline for sending in an AP model like the 15400 for service? (Ex: Every 5, 7, 10 years?) What does a standard service run? How long is the turnaround?Just because I’m sure this will be suggested... I used the search function and didn’t find concrete answers, and most of the threads were 5 or more years old...Thanks in advance.
