Which one I'd pick
New vs pre-owned: at $475 new with a warranty, there's little reason to buy pre-owned unless you find a mint one well under $400.
What to check before you buy
- Size: it's 45 mm across, but the cushion case and short lugs wear smaller. Try it on if you can.
- Crystal: the SRPE93 uses Seiko's Hardlex crystal, not sapphire, so check it for scratches on a used one.
- Fakes and mods: modded Turtles are common on the used market. Check that the dial, bezel and movement are original.
Alternatives worth a look
- Seiko Prospex Alpinist: Seiko's other cult classic, with a compass bezel. (39.5 mm stainless steel, Calibre 6R35, retail $900 (current SPB507, Seiko US))
- Tissot PRX Powermatic 80: A Swiss automatic for a little more. (40 mm stainless steel, Powermatic 80, retail $850 (40 mm))
- Oris Aquis Date Calibre 400: Step up to a Swiss diver with a 5-day movement. (41.5 mm stainless steel, Oris Calibre 400, retail $3,900 (Oris US))
History
Seiko's original 'Turtle' arrived in 1976: the 6306 for Japan and the 6309 for export, a cushion-cased automatic diver made through 1988.
Seiko brought the design back in 2016 under Prospex as the SRP777, keeping the cushion case and dial but using the 4R36 movement and 200 m water resistance.
The SRPE93 is the current black version, with the automatic 4R36 (manual winding too), about 41 hours of power reserve and a Hardlex crystal.
