The Seiko India website lists the country of origin and manufacturer of individual Seiko models to comply with India’s import laws. None of this is surprising, and mostly just confirms what was already assumed.
Note that this is just the factory the finished product leaves, Seiko Watch Corp. and Seiko Epson Corp both own multiple production sites all over the world, and a large network of third party suppliers, many of which are unknown.
No watches originate from Malaysia or Singapore, though SII and Epson Precision Malaysia both operate watch factories there, presumably making parts, not complete watches.

Japan (Epson)

- A handful of presage with special dials.
Thailand (Epson Precision Thailand)

Wouldn't EVs be more like the Swiss quartz movements that beat the Japanese and Swiss mechanicals (which would be ICE)?
You didn't account for the price difference between the watches you mentioned and the Seiko
The Seikos with the -10/+15 spec have the L movements and are generally over $3000
- That is 4 times the price of a PRX
- That's more than 4 times the price of a Hamilton Kahki
- Almost 3 times the cost of a CW12
- 1.5 times as much as a Longines Conquest
Crazy coincidence how so many brands have the same "in-house movement" these days
The anti-magnetism part of the METAS testing is particularly silly, completely pointless and just for marketing.
The ETA 7750 is a lot better designed than the El Primero, it would be perfect if it wasn't so thick.
How are these even on backorder? The price is very high.
Looks like a 563036SA
Does this not have a dial? Looks like its just paint on the crystal.
Is there a dial code on the disks?
You're correct, case finishing doesn't change much. The case construction does change quite a bit though, and applying the finish can take a lot more effort.
