Not my first choice of watch, but what watch would you rather have for the zombie apocalypse?

That reminds me of a lot of different watches that’s pretty cool. That case is wild, it is on the edge of failing but it succeeds very well because it’s clean and everything just goes together.

Never thought I’d really like a red dial but wow. Beauty.

Cheaper movements need to be tuned carefully. Seiko can and does make one of the most accurate mechanical movements in the world, the Grand Seiko.

It is 100% mechanical watch driven by a flywheel whose accuracy is regulated by an electromagnet connected to a crystal. Accuracy is typically +/-1 sec per day.

The Quartz Tuna is +/- 0.5 sec per day.

The cheap movements like the NHxxx https://calibercorner.com/seiko-caliber-nh34/

Are in I can’t even estimate how many watches. A great many. It’s accuracy from the factory as you can see is +40/-20 sec per day. The movement however CAN be tuned to +/- 10 sec per day but it is a mass produced watch and time is money. The other thing is that this watch has a general lifetime of around 10-15 years. It’s cheaper to just replace the movement than to have it serviced. Movement is around $40-$60

There are 26 calibers of Seiko watches. The upper range would be Presage and then Prospex and the top being Grand Seiko. So it really depends on the particular watch and the particular movement.
