Been looking around WUS for some used pieces but not very often they come up. And when they do, it gets sold rather soon.
Depreciation of these TUNAs are very small too.
From what I gather, SBBN017 is the lowest priced TUNA (Hardlex crystal, Stainless Steel bezel, 300M). Then comes SBBN015 (Dual Hardlex, black bezel, 300M). And SBBN013 (Crystal, black bezel, 600M).
I don't think my info is correct, please advise if they are wrong. There are also many more variants and LE in the market.
But what I want to know is, are the TUNAs sold in Japan cheaper than Malaysia/Singapore/USA/etc.
Maybe an Airasia trip to land of the rising sun to get a TUNA, no?
Hi Toolkit, too many L.E. Tunas to mention every single one... The main ones you need to know, in approximate chronological order, are asa follows:
6159, 600 m WR - First Tuna, late 60s, with hi-beat auto movement.
7549, 600 m - First quartz Tuna. 'Golden Tuna'.
7549, 1000 m - Golden Tuna. Same watch as 600 m 7549 but Seiko increased the water resistance testing to 1,000 m, so could increases rated depth.
7549, 300 m - Quartz Tuna. No gold bits.
7C43, 1000 m - Golden Tuna. Seiko introduces current family of high torque dive watch specific quartz movements. Best dive watch movements in the world IMO.
7C43, 200 m. Quartz, no gold. Not sure why depth rating was lowered. Most likely just a change in WR testing.
7C46, 1000 m. Darth Tuna. Current movement, mostly black ceramic. Movement upgrade (longer PR I think, 5 years).
7C46, 300 m. Quartz, no gold, back to 300 m.
SBDX005, 600 m - LE reissue of original 6159 (1000 made), but with 8L35 auto inside.
SBDX011 - Auto 'Emperor' Tuna. Not golden, more like Darth.
7C43, 1000 m. Golden Tuna. Limited re-issue in Taiwanese market.
SBDB008, SBDB009, 1000 m - Spring drive Tunas. LE and standard model.
The main points to understand are that most Tunas are quartz, with a 200 / 300 m family and a 600 / 1000 m family. Fewer autos, although they have become standard models since maybe 2008 or so (Emperor Tuna). The SD Tuna was released last year as LE, now released as a standard model. Hope this info is useful.
