In the workshop not so long ago was this lovely little Tag Monaco, featuring the Cal 17 or ETA 2894-2. The watch was due a service and light overhaul to the cosmetics so without further ado.....
After stripping down the casing it is clear now just how much gunk can build up inside the recesses of the watch. The pushers were also removed so that they could also be given the proper attention and improve their effectiveness. A good soak in the ultrasonic will clear all this gunk away no problem.
With the casing cleaning we can strip the movement down, lets take a look at the chrono module which fits atop the movement....
The movement photos below show most of the steps of the strip down, whilst some may not be in exact order you should get an idea of the basics :)
With the movement serviced and casing parts all cleaned up it was time to put it all back together, yes all those lovely screws :)
Everything together and running smooth the watch is ready to return and be used again. Despite the case cleaning there was still some staining but since this is hidden it's not too bad. Most people would think watches are impervious to dirt getting into those fine lines but believe me any fine crack makes a nice home for dirt, so lesson here ? Keep your watches clean :)
