Backwind Gold Omega

We recently repaired this interesting gold Omega watch. As you can see from the picture, this timepiece does not have the conventional crown (winder) located in the 3 o’clock position. Hand setting and winding is instead done using a winder located on the reverse of the watch. Hence such timepieces are known as “backwinders”.The movement (mechanism) is an Omega calibre 440, which is the backwind version of the calibre 580. It’s a 17 jewel, incabloc shock protected movement, which runs at 21,600 vibrations per hour.

This particular watch showed signs of historic water ingress, so required a full service and a number of replacement parts. The movement was fully disassembled before being cleaned in our Greiner ACS 900 ultrasonic watch cleaning machine. After a clean and inspection of each part (replacing anything damaged/worn) it’s time for reassembly. The movement is carefully put back together, with a new mainspring fitted to ensure a reliable source of power. During reassembly the watch is carefully oiled using tiny amounts of specialist oils designed for such timepieces.

Alongside the servicing of the movement, the case and bracelet were given some attention. These were given a light buff and polish, before an ultrasonic and steam clean.

There was also significant discolouration to the dial on its arrival with us – again, due to the historic water ingress. We had the dial fully restored back to excellent condition.

After refitting the dial and hands to the movement, the watch is reassembled. A beautiful timepiece restored to continue providing many years of reliable service.
