Do you have a specific watch you’d recommend?
If you are getting started with mechanical watches buy an Orient watch (https://orient-watch.com/). You can get one for < $200.
When you want to upgrade - Nomos (https://nomos-glashuette.com/en). $2500 +
Above this is what you can afford but always look for "independent watchmaker + in-house movement".
I also like the designs of Junghans (https://www.junghans.de/en/) but they use a thrid party movement.
My friend is completely crazy about mechanical watches and recommended me getting ~4000€ upcoming watch coming from reputable but not well recognized Italian watchmaker.
They came after few months. Till this day he loves it - and it’s one of his favorites. For myself it was kind of meh and I stopped wearing it after a year or two.
Some years later I Was gifted TAG Heuer and I noticed one thing: that expensive watch main function is signaling. It wasn’t only a time device, but widely recognized jewelry and was a conversation piece.
And a watch today is ultimately useless gadget. Clocks are everywhere and everyone has a pocket watch in a form of smartphone. Taking signaling away only makes such expensive gadget even more useless.
So, like kinda? They're more like a cousin than a sister brand, though.
