At The Bench: The Restoration Of A Tudor Advisor (Reference 7926)

Recently I have built up an irrational interest in wrist cautions. I had been reestablishing some JLC Memovoxes and the fantastically disappointing Seiko Bellmatics when I discovered this “for fix” Tudor Advisor on eBay. It was not so great and not working, so for me it appeared to be a decent adventure. 

The Tudor reference 7926 was underway from 1957 until its substitution by the reference 10050 in around 1969. This previous form included the Tudor Rose as opposed to the Shield. It was likewise housed in a 34 mm shellfish case. What truly drew me to this example was that it went ahead its unique bolted band. 

When it showed up and I played out my superficial review, it became obvious that an incredible arrangement was wrong with this piece. The watch hands were affecting implying that the second hand was stalling out on the moment hand and halting the watch. The precious stone was scratched and shady, the alert stem was trapped, the time wouldn’t set dependably, and that was only my prompt perceptions from the outside. 

Once I got it separated I found the genuine degree of the fixes required. Dismantling the dial side of the development I previously saw that the moment wheel was feeling the loss of a decent segment of its teeth. Now there is a two-crease issue to discovering something like this in a watch. There is the most clear issue which is the wrecked part, yet then there is the second and at times seriously harming issue of ensuring the missing teeth have not harmed the remainder of the development as they drift around. The second issue I found on this piece of the development was a wrecked screw. Whereas the messed up moment wheel was a straightforward expulsion and substitution, now and again getting a screw out of a watch primary plate can be a fragile and extensive cycle. To make an already difficult situation even worse, somebody before me had endeavored expulsion, making my work marginally more irritating than it must be. The screw size made it difficult to utilize typical apparatuses for this reason thus I needed to turn to more extraordinary measures. Utilizing two boring tools I initial drilled a little opening through the focal point of the screw, I at that point turned the development over, and utilizing a marginally bigger boring apparatus got sufficient grinding to tenderly eliminate the screw without causing any (extra) harm to the fundamental plate. With the screw extricated I got to review. Shockingly the whole stuff train and caution mechanism looked incredible. I simply required a new moment wheel, screw, heart , and gem (I’ll return to the crystal).

A earlier watchmaker fell flat to separate the wrecked screw. 

When I say the pieces are little I’m not misrepresenting. Here is a penny for scale

The hollowed remainders of the extricated screw. 

After an extremely intensive cleaning, oiling, and re-gathering, I could at last appreciate this development. It utilizes an ebauche from a company called A. Schild. This company delivered an immense volume of watch developments prior to being converged into ETA in the last part of the 1970s when they, as most other mechanical creators, were bankrupted by the quartz upheaval. The base-type of the development is the AS 1475. The caution complication works by spring stacking a bunch of wheels and opening them at a time defined by the situation of a huge wheel set on the standard game plan of the movement works. A wheel that takes after a star at that point quickly turns moving the sledge to and fro against a post fixed working on this issue back. 

The AS 1475 contrasts from numerous points of view, yet most eminent is its size distinction comparative with its friends (Vulcain Cricket 120, and Memovox 489). The Memovox and Cricket are just around 28 mm and the AS is 25.6 mm. The fascinating thing for me with these old alert developments is how they figure out how to actually fit a fairly massive complication into a little bundle. The caution requires an altogether independent origin to store the energy for the gong. Also, there is an enormous chunk of steel that necessities to move quick and far enough to make an adequately discernible sound. It is a fascinating issue that each brand has their way of finessing. This specific one compacts and stacks the stuff train to allow for the extra components. While my previous portrayal may have sounded somewhat desperate, the whole thing returned together perfectly and truly looks stunning.

Mechanically the watch was fit as a fiddle, so I directed my concentration toward the hands . As I referenced before the hands were affecting. This is by and large the aftereffect of one of two things. Either the hands were inappropriately set, or the second hand is excessively free thus it goes excessively far down on the post it should fit cozily on. This watch had the last issue. Watchmaking is at times alluded to as “the exchange of 1,000 apparatuses” and this is an incredible example of that. There is a particular apparatus made only for fixing hands. When fixed and refit the hands moved beautifully. 

Prior to packaging, the gem must be supplanted. It was at this crossroads that I had a choice to make: conventional or veritable. For me the choice was self-evident. On the off chance that accessible I always go certified, but since these precious stones are not stamped, if this were for another person, they would probably have no chance to get of figuring out what I had introduced. This is an incredible occasion to accentuate the trust that you should hope to discover in an extraordinary and legit watchmaker. The value contrast ($7.50 versus $40) makes it a captivating trick to charge for certified however introduce conventional. A decent way to check is to always request the bundling your parts came in. 

Finally all back together this reestablished excellence was all that I search for in my reclamation purchases. It was loaded with issues, challenging, had some good times and valuable complication, and came out looking perfect. I can’t request more than that.
