Service: Roamer Rockshell Mark II / ETA2789-1

IMG_3382David sent in this great looking Roamer – you just have to love the case, dial and hands. All in pretty good condition, but it needs a service. The crystal is also a bit scratches, so that will get a polish, too.IMG_3383

The case back is held in place by four screws.IMG_3384

The case back comes out of the case with the crystal and everything, so there will be a split winding stem.IMG_3391

The amplitude is very low, so the movement definitely needs a service.IMG_3392

The ETA 2789-1 has a day and date display.IMG_3475

The new mainspring goes into the barrel, after having applied the usual braking grease to the barrel wall.IMG_3477

The base movement is ticking again – let’s see what the timegrapher says.IMG_3478

Good old ETA never disappoints!IMG_3479

The bottom plate comes back together.IMG_3482

With the crystal polished, the watch is looking very swish again!

  1. … really like that seconds hand! And the bracelet, and … well, the watch in general I suppose. I guess you’re not too happy should you break the crystal, though.

  2. As said, very 1970’s …. I took a punt last year on a Roamer Searock, MST522 movement, with a round crystal and heavy stainless bracelet. It is currently my day to day watch as I am working on the bracelet one link at a time. Looks like the steel links on this one are nice and tight.
    Surprised to find out that Roamer worked with Tissot and Certina on the later in house movements, MST 520 – 523
    Very nice watch, even nicer now Christian has serviced it !!


  3. That’s a smart looking thing – very 70s! Just my sort of thing 😉

    Was the case-back missing one of it’s screws?
