The Omega ST 366.0848 Seamaster was introduced in 1976 under the ‘International Collection’ and lasted well into the first half of the 1980’s. It remained unchanged except the dial was updated to the modern Omega logo toward the end of production. My example pictured here is an updated dial version and dates to 1984, see my Omega date calendar, the watch is totally original, with signed crown, clasp and even the original hesalite crystal has the Omega logo.
(Sorry about the reflection that seems to make some batons seem gold coloured, they are silver coloured)
The Omega Seamaster ST 366.0848 has a calibre 1020 Omega in-house, day/date movement, with quick set day and date, with hacking (can set the second hand) the case is 35mm in diameter, and 37.7mm with crown, but it wears bigger, helped by the larger lug to lug size. It is documented Omega produced the 10xx series with cost cutting in mind, the movement is not finished to the degree of quality found in the 1520, but the 1020 is still a fine movement with very good long-term reliability. Over half a million were made in its decade-long production run and it seems to be well regarded among fellow collectors, I am very pleased to be adding it to my collection and 32 years later it is still going strong!. The 1020 is a 28,800 bph, that equals 8 beats per second that provides the legendary smooth sweep second hand, with 17 jewels with a generous 42 hour power reserve.

The 1286/249 bracelet is shared with a few other models but mainly this style of squared-off case. The removable links are tandem and held in place by pins. The pins are easily removed unlike other Omegas of the era. Omega bracelets usually are very solid and this one is no exception, and after 30 odd years of wear, it’s still wears very tight and very comfortable.
One word sums this watch up originality!
Lovely Seamaster Sea-horse back-case logo…lovely! The Omega Seamaster ST 366.0848 case back is very nicely detailed with the Omega Hippocampus. For some reason, Omega felt 30m of water resistance would be enough, 30m of water resistance and a name like Seamaster are not a perfect match, but I would never take it any where near the sink never mind swimming/diving so it does not bother me.
