Longines Calibre 12.68Z model 7033-4 – Service and restoration

Nick sent me this vintage Longines watch for a service and restoration. I have already featured an almost identical watch on the blog in this article. The service on that particular watch had been perfectly straightforward, but in the case of Nick’s watch it turned out to be a little more complicated as you are about to find out….

Longines Hydroconquest Calibre L633.5 (ETA 2824-2) Service

I have already featured several vintage Longines on the blog, so I thought I would write a post about the service of this “modern” Longines Hydroconquest. It is an Automatic Diver’s watch, powered by Longines’ calibre L633.5. As you will see, this movement is actually an ETA 2824-2.

The watch looks very smart indeed, and I am impressed by the build standard, it has a real quality feel to it. It came for a service. The crown was very stiff when winding or setting the time, so I will be investigating this as well.

Longines Calibre 284 Service

This week I have decided to feature another vintage Longines as they are such a pleasure to work on. This particular watch has a 9ct solid cold case and caseback, and it is powered by a Longines Calibre 284 movement. Very much like the Calibre 12.68Z I featured on the blog recently, this movement is from an era when Longines were very much at the high end of the market. The level of finish is very high.
