After a spate of vintage restorations making their way through the door, I have had a few modern watches come through. Up today is an Omega Speedmaster with the 1861 movement. It was a straightforward overhaul with only a few parts needed. It needed a new setting lever screw and operating lever.Continue reading “Overhaul Procedure – Omega Speedmaster (Omega 1861)”
Up today is a fairly straightforward overhaul of an Omega Seamaster 300 with an Omega 1120 movement. An 1120 movement is basically a glorified ETA 2892. There are a few differences that Omega made, but nothing major. The ETA 2892 is a great workhorse of a movement which doesn’t always get a lot of love, but it’s a solid caliber.
Here is the watch in question.Continue reading “Overhaul Procedure – Omega Seamaster 300 (Omega 1120)”
Re-bushing a barrel is such a crucial aspect of watch servicing, but it is seldom done. Anytime a watch doesn’t have a jeweled barrel or center wheel, there will be wear.
A barrel and center wheel have steel arbors or pivots. When they use a jeweled bearing the jewel is the harder of the two materials. When they just sit in the brass mainplate and bridge the steel is the harder of the materials.
Due to this fact, the plates wear before the pivots and arbors.
When this happens the plates must be drilled out and new brass bushings need to be installed.
The arrows below point to the plates that have worn holes. That is where we will drill and install the bushings.Continue reading “Re-Bushing A Barrel – Omega Speedmaster 321”
There is nothing more unsightly than watch movement screws that have been hacked to oblivion my sloppy workmanship. It is, sadly, something that is seen far too often in watch movements that I come across. We can take the below Omega Speedmaster as a perfect example. This reference happened to be 2998-1, a very rare and expensive Speedmaster reference. You can see below how bad the screws were. Fortunately, all was not lost and the original screws could be polished.Continue reading “Black Polishing Screws – Omega Speedmaster (321)”
This Omega Speedmaster recently came across my workbench.
It was in quite a bad way and needed bushings installed for the upper and lower barrel and the upper and lower center wheel. It also had excessive wear on the minute wheel post and the intermediate minute wheel post. Unfortunately, jobs like this are usually neglected by watchmakers and cause poor performance of serviced watches.Continue reading “Remove/Replace Worn Minute Wheel Post – Omega Speedmaster (321)”
