A relic of the Jewel Wars, this 35mm 1950s Mount Royal with an 80 jewels (kind of) Felsa 4002, 21 of which are broadly functional and 59 which, er, aren’t. I’ve no idea how many of these watches survive today or, indeed, were ever made but it “coulda been a contender” until the likes of Waltham, Orient, and Titoni climbed into the ring with their 100 (and more) jewelled efforts.

Of the two recorded makers of a Mount Royal brand, Choisi seems to be the most likely candidate for today’s curiosity, it being a product of the original company founded in 1929 before its demise, date unknown. The company name was seemingly reactivated in 2013 by a Singapore-owned  enterprise which, from what I can see, is largely producing retro-style watches along with homages based on the old company’s vintage models. 

Regards.

My 1961 Omega Constellation. Hard to believe its 60 years old. I don't think the Omega bracelet is correct . I believe these types came out in 62'. Doesn't matter since I like these more squared grain

Today.... My 1940's Heuer Ref 347. Rugged looking watch with its battle scared dial. It has a Valjoux 22 under the hood. It's quite a large case for the time which gives it more of a contemporary

Just finished servicing my Zodiac Rotographic containing an AS 1624 automatic movement. 35mm and a really nicely coloured dial.

I see it says "T Swiss - LIC ATO"

The ATO patented movement is about as simple as these things get. At its most basic, it only uses one transistor. This may not make for the most stable oscillator, design but in this use case, they are actually relatively good, since they rely on a fairly conventional mechanical balance to control the oscillator frequency, rather than an R/C circuit, which would typically be less stable over the working temperature range.

This AC125 germanium transistor version is probably the most simplified schematic, but often in reality there are current limiting resistors and other little tweaks.

Since they have no mechanical switched contacts, they don't suffer from burn through or oxidation failures of the contact.

37.5mm Swiss-made Stuag, wears very flat and runs on a 17j ETA 900. Probably late ‘40s.

Attributed to one of the few female (is that term still allowed these days?) -led watch manufacturers, Mlle Mireille Grebler (later Mme Mireille Franz-Grebler) who also came to control Cauny, before that particular brand became Spanish owned sometime in the 1970s.

Regards.

Yesterday's eBay deliveries.

A nice pin pallet that's the cleanest I've ever seen, came with the pallet fork loose, refitted and ticking away, will get a service and back onto eBay at some point.

Then an 'interesting' Seiko franken.

Lovely clean 7019A movement, (which was the reason for the purchase) bonus of new strap, practise dial to strip and make a dial from and hands.

My second of this VEC brand and driven by a 15j Cupillard 233, the other one running on a 17J Lorsa P72. Brand name registered in 1932 by SR Ltd Etablissements of Marseilles, the city from where I bought this one, so no doubting its French Connection.

I’ll get my coat.

Sure.

The Rodeo is here ->

The "Li Jac" is here ->

Both have remarkably similar movements. The "Li jac" is a simpler un-jeweled version, the "Rodeo" is jeweled.

Fero ??? Have just bought this because I like the face ! Never heard of this watch and it is a none runner. Any information would be much appreciated. Cost £28.54 Inc postage so wasn't too painful. Not sure if it's franken or worth its price?

Blimey, I see what you mean.

What you've got there would appear to be two French-made Framelac pin-levers, a movement maker about which very little seems to be recorded. I've attached an image from the Uhrforum.de of the jewelled-lever FR 304 for comparison of the bridge configuration (similar) and the shape of the balance cock (identical).

    • Hi Check out this link   http://www.dirkfassbender.de/dial-feet-soldering-machine.html.   I build one of these and it works very well , there was a topic on the site regarding this subject.  The ones featured similar to the one I build for about £25 does the job and there is no harm to the dial surface. check out the search on site top right for the topics.
    • Can anyone mention one single change made to a forum/ computer /chat program /to anything which was broadly accepted by the user communities and not ended up like this change here? (I wont accept examples from North Korea.) By now I believe that Mark should have earned our trust to accept his decisions without a word. This enhancement did not hurt anyone, did not cost anybody, you were free to use it or not to use it. I don't mind if it goes away or it stays, we should not spend much of our time on it.  Quote from the Time Savings Clock post: "In fact, time isn’t just an equal among other things of value. Time has a worth that’s in a class by itself because  there’s only a limited amount of it.  And unlike many things that can be bought with money, time isn’t one of them. That makes time very precious. And when I get to thinking just how precious it is, I also get to asking myself how well I’m using it. And that leads me to other questions, about loved ones, the future…in fact the very purpose of life." And another relevant youtube video: "Hello Suzy, can I be a mountain leopard please?" from 2:30  
    • @Nucejoe - What in the actual *** are you talking about. Your comments are completely non-sensical. @jdm has been attempting to assure me that you are trying to be humorous. I have to say - the joke if any is completely lost on me especially in the context of your PM to my inbox. Wrong!!! This was not a test run where the trusted members were a test batch. This was intended to be an enhancement to the forum for TRUSTED members to be able to communicate the requirement for certain parts they may be finding it hard to obtain.  Absolutely no idea where you got this idea from - what "First Purchase" the forum is not selling anything joe!!  It seems to be you completely and utterly misinterpreted what was trying to be achieved.    To the OP @Marc, and @Tudor I may well still implement the idea, but I am rethinking things and may put it to a poll and let the membership decide on this, after all - this is a community. I am very sorry about that @Tudor It really was not my intention to disrupt, but things need to be rethought. On the plus side, it seems we are on the right wavelength regarding the community helping each other with hard to obtain parts. It seemed like a natural progression to me.   Advanced Member is free - there is no charge - where he got that from I have no idea. Perhaps because people who have provided financial support for the forum also have access? Well yes - that was intended but why not? They support the site and we should thank them for it.    
    • So the contention is that it's free to use the advanced members section, or that people will be looking for free tools/parts, or ___?
    • Oh please Jdm,  lets keep this going, a solution might be found.
