A named, in-production 4R36 with a published $176 overhaul, 100m and Seiko's three-year warranty — the most serviceable cheap watch there is.
Hardlex rather than sapphire, and 41 hours of reserve.
The 4R36 is the most commonly serviced mechanical caliber in the United States and Seiko publishes a flat $176 price to overhaul it. That single fact does more for a twenty-year horizon than any spec on the case.
