Omega 14390-4SC "Seamaster"
Omega · 14390-4SC · 1960
About this model
The Seamaster of 1960 was a dress watch, not a diver. Omega launched the name in 1948 on watches built to survive water, and by the end of the fifties it had grown into the everyday Omega: a thin steel case, a clean dial, and enough robustness to be worn without thinking about it. The 14390 ran from about 1959 to 1962. Inside sits the calibre 285, part of Omega's 30 mm family descended from the 30T2, a manual movement with a reputation built on being repairable and hard to knock out of adjustment rather than on complication.
What you're looking at
Dial with applied Omega logo and applied indices; the Omega wordmark and Seamaster are painted. Slightly uneven patina but an attractive whole. Lume remains on the hands but is probably on its way out. The acrylic crystal is hazy but unscratched and should polish out. Small marks on the side of one lug, judged polishable. No other scratches on the case.
What I know is wrong with it
A movement screw is broken. The stub remains in the hole and the clamp holding the movement against the case is still present; the stub must be extracted before the movement can sit securely in the case.
No watch here has been pressure-tested. A period WATERPROOF or WATER RESISTANT stamp says nothing about the seals today, so treat every watch on this site as not water resistant.
