In for service recently was this classic Omega, having not received any attention for over 15 years the watch was performing less than ideal. The movement was pretty good but there were some gremlins that needed attention first, lets take a look on the inside first. >
On closer inspection i find the helium valve is damaged and so water has found its way inside the watch, fortunately the movement ring has stopped it fully penetrating the inner workings. Lets look at the rust damage. >
The stem had suffered with rust as well but as it had not broken i could treat it and remove the rust, ideally both crown and stem should be replaced but at cost of £100+ it was decided to keep the original until such time it gave way. The helium valve was also damaged but after a good clean out and use of some silicon grease it would be time to test the watches water resistance, starting at only 30M. >
The casing was given a thorough clean and then assembled without the movement, everything snugged down tight it was time to test it starting at a low 30 Meters ( watch should resist 300M ).>
The watch was kept under 30M pressure for 15 minutes before releasing the air and from the photo above we can clearly see it has failed. Air escaping from under the bezel is just normal trapped air but the valve despite cleaning and grease could not stand even 30M of pressure. As the cost of replacement parts is high again the valve was not replaced, best i could do was to pack it with special water repellent grease.
With the tests complete the movement could be stripped down for cleaning and service, whilst rust was not overly present you can see from photos the movement has some considerable debris inside. >
With the movement cleaned and assembled the immediate results looked great, after a few days testing it could be adjusted and sent on home. >
With the watch thoroughly cleaned, movement fully serviced and running great, this Omega was ready to return home and go back to working life. Not all water damaged watches can be saved but on this occasion it was sent in just in time, whilst not perfect the watch is very functional and will keep great time for many years.
A well maintained watch will last many lifetimes so remember to keep them serviced every 3-5 years :)
Next feature will be the Seiko 5717-8990 so if you've been waiting for that one check back soon !
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 :)
Check back again for more posts :)
So many watches since the last post its hard to know where to start, so lets start with a Rolex :)
These older models are always a favourite, simple, reliable, and high quality throughout. The movement is the classic 1530 calibre, automatic with no date or complications, so lets take a look at the movement >
We start off by uncasing the movement and removing the hands, from there we can strip down the movement and check for any wear or damage >
With the hands off we can set about removing the dial and stripping back the dial side parts ( except winding parts ). We must make sure once the automatic bridge is removed to power down the movement, movements under tension when stripping down is not what you want >
With the movement stripped down and cleaned the mainspring was changed for a new one and the whole movement re assembled and lubricated. Timing as to be expected is excellent, very rarely do Rolex watches develop issues more commonly found on lesser Swiss watches, not to say other brands don't make exceptional pieces but Rolex do have that edge. The casing on this watch is kept original , warts n all , the bracelet was given a very light hand brush to bring back some of the brightness, the glass lightly re polished and shes ready to go back.
Truly a stunning watch and now back in top running order :)

Having family commitments as well as a very busy workshop sometimes it leaves me with less time than id like to add new and interesting posts to this blog, however it's been a while so here's some fresh new posts coming up to entertain you all :)
The Seiko Alpinist is a truly great little watch and certainly a popular piece whether your a collector or not, with great looks and a reliable proven mechanical history ( 7S26 onwards etc ) its certainly a winner. Almost sad now that they are no longer made or sold but if you look online your sure to find one or two crop up, even when they do you will part with a small sum for what is a great tool watch.
Without doubt a great looking watch, nothing overly complicated just simple and practical with a few useful features thrown in. The look of the watch is somewhat of a mix between new and old, the skeleton hands add to that vintage style look and the casing shape is not too dissimilar to older styles either. With a 6R15 calibre, Seiko have built on their 7SXX/4RXX success and improved on it, manual winding, hacking seconds, rapid date, and well known reliability and timekeeping, so what more could you need :)
So how does that rotating bezel work ??
Plastic is often looked upon now as an inferior material and although full metal gear and bezel would be nice they would add to the cost. Further to cost, metal would require some sort of lubrication to keep it turning smooth and reduce wear, fortunately some plastics have self lubricating properties so this is likely the reasoning behind plastic for the gear and bezel ( aside from cost of course ). So let's get the movement out and see the finish on that dial....
The movement used in this watch is a great choice, whilst similar in appearance to the famous 7S26 the 6R15 does have a few extra parts and functions so requires a little more effort to service than its younger generation. Overall the movement is a well engineered marvel, take the success of the earlier design and add real usable features such as hacking and manual winding, a few extras parts and a few simple changes and voila ! For those who want to see the full strip down view the photo gallery below >
When the watch arrived it was running 30/60 seconds slow a day but after service it was running a absolute treat, the casing was given a light clean and the whole watch put back together ready for working life again. Having owned many many Seiko's i surprise myself for never having owned one of these, perhaps one day i will but for now returning this one to its happy owner will suffice :)
On occasion i do get a brain fart and forget to take photos after a service is finished, so this time no after shots, big apologies , will do better next time :)
