So i really wonder if this statement is actually true, that 1k watches have better accuracy than +15/-10 Sec. Does watches in this price range really state their accuracy and have good accuracy that makes Seiko watches look over priced.

You’re simply not looking hard enough.

Watches with chronometer grade accuracy below 1k:

Personal Rant: if accuracy is so important why don’t u just buy a 50 bucks quartz and be done with it instead of going into mechanical watch.

Yeah, this opinion is as “personal” as a Rolex production line. So many people will spout this nonsense, while claiming that they like mechanical watches for the “romantic soul” and the “beating heart of the movement”. If you care so much about the movement to justify paying 5x the price of a quartz model, why do you not care if it functions well or not?

Saying you’re into mechanical watches because you care about the movement, then saying accuracy doesn’t matter is like saying you love Italian food and then only eating at the Olive Garden.

Me at the dealership, after asking the dealer to pop open the hood and show me the engine:

"yep, that’s an engine. "
