Because OF seems to have the best UG forum, I decided to post this here. This is an edited version (and possibly condensed) of posts that first appeared on https://canwatchco.ca/ and WUS. As of writing this, the project is complete (yas!) and I'll probably post in stages due to time and space considerations. I'm wearing the beautiful and finished watch to an xmas even dinner in less than an hour, any excuse to break out this UG!

Post 1: End of June, 2025

A thread to document an ongoing project from an estate sale:

The Buy-Side
I have an auction problem. I like deals, I like the hunt, and I like parsing through the junk for the gems (or gem-ish). It's genetic, from my Mother's side.

I like the estate sale "dresser top" lot. Always the possibility for something truly good lurking amongst the junk like this lot of "Men's Accessories" In the midst of all the photos, a decent shot of this watch, clearly in filthy condition with an incorrect crown. No way to tell if it was running from the other photos (top tip, always check other photos to see if the seconds has advanced).


Some research shows a nice one looks like this or this and in "great" condition sellers are asking over CAD$2k (as of posting).

Pondering things, I realize the pick up (no shipping) is on a nice summer Saturday when I have a space to take a little road trip to a delightful part of the province and dip my toes in Lake Erie.

Winning bid of $70.11. Add in fees, taxes, half a tank of gas and some snacks, the watch probably owes me CAD$150, max.

Plus it came with this other great junk:

The old boy had a thing for cufflinks, tie clips (including a really cool one with a machine screw on it) and some other watches. Also included: a Hamilton Electric (505 movement) and a vintage Solar (an Eaton's house brand) with a Swiss movement (sadly not a Solar Oyster aka store-brand Rolex).

Filthy But Kinda Runs
The UG was filthy, runs (but not well) when wound and had been worked on (incorrect crown):


Microtor-less....
Yes, the UG micro-rotor is know by the trade name "Microtor".

Popping it open revealed a fun fact:
  • The Microtor went bad at some point (see witness marks on case back) and it was simply removed to run as stem-winder!


My guess, the Microtor wore out and went bad a some point in time (pre-internet) when it was hard to track down Microtor parts and (in the area it came from) there wasn't a watchmaker who could get those parts.

Fortunately, the authoritative Pole Router site has a fantastic article about worn Microtors for the cal. 1-69 and its relations:
Repairing a worn Microtor - from calibers 215-218-68-69 - The Polerouter Reference Website

With that info in-hand, I've purchased a Microtor (complete) which is alleged to be from a 215 and to fit. It is somewhere, on its way from Europe.

What is this Watch?
Described by one owner as a "Pole Router hiding in plain sight", the cal. 1-69 is most famous for that watch. This watch has the 28 jewel version of the 1-69 with the "Girocap combined settings for escapement wheel if 28 jewels", i.e. shock protection for the escapement wheel.

This is a dressier and square late 60s/early 70s version. It wouldn't have any water-resistance due to the snap style clam shell case and isn't marked as such. Based on 5 minutes of Top Quality Internet Research the reference and its relations was made in numerous dial/indices/case combinations and we can see variations to the earlier UG logo (the "fat U" logo on some of the comparison models was 1960-65 and followed by the thin U in the box).
I dig that "tiger eye" and gold combo.

Next Steps
My intent is enjoy this late 60s dress watch gem, a watch I'd never purchase at market prices.
  1. Blow it apart and clean it (mostly done, post to follow).
  2. See if the Microtor complete arrives, works and fits.
  3. Locate a crown and possibly a stem (must do some measuring)
  4. Service (by a professional and not me).
  5. Band or bracelet?
  6. Wear and enjoy!

Thanks and regards,

Post 2: Mid-July, 2025

Time for an update (and with thanks for asking!)

Parts [I was] Looking For:
I'm learning that lots of UG parts are unobtainium as NoS or generic parts.
  • UG p/n 1496 for 215/218 - the stem/axel around with the Microtor oscillates
  • Weird "chubby square" crystal that I can't seem to locate at any supplier.
    • Each side is rounded out beyond the vertices of the square

Parts on Order
I've got a (hopefully after some measuring) a correct crown on the way:


Microtor Update
Yes, the 215 Microtor arrived, fits, is a bolt-in replacement and winds the mainspring. With thanks to wonderful French ebayer of watch parts who had it in stock, including the mounting screws!

The data here re interchange Repairing a worn Microtor - from calibers 215-218-68-69 - The Polerouter Reference Website is truthful! The 215/218 Microtor is the "Type 1" with a stem/axle rotation and a 68 or 69 should have a Type 2 with bearing rotation. I'm not hung up on tradition, however, and this isn't a numbers-matching resto.

However, I [was] searching for part 1496, the stem/axle as I can't tell whether this one is a bit worn. Will be for a watchmaker to sort.

Crystal
I've done a multi-step (automotive sandpaper and polywatch) resto of the crystal that was glued into the case. There's a small crack and very deep scratch BUT I can't seem to locate another at the usual suppliers. It may have to solider on (need to order some Hypo-cement).

My detailed technical drawing on a post-it shows a 25mm square that "rounds out" on each side to ~27.2mm.

Dial
Have been watching and reading up on dial resto. This one seems to have oil or spots on it and be too far gone for anything other than a gentle Rodico treatment. Need to order a very soft brush and try BUT it'll be what it'll be.

Shown here with an Aquastar friend (another cheap auction find that took some careful parts assembly and service to get to a happy level.

The Joy of Bulk Lots
Thanks to some sales of other items that came with it, principally a non-running Hamilton Electric Skip Jack and some Masonic ephemera, the Micorotor was almost free! In due time I'll flog more of it.

Thanks for reading!

Thanks, a super neat Hamilton Skip Jack 505 Electric (non running).

Post 3: Mid-August, 2025
Some parts arrived and I had some time to play with this watch; update post!

Dial and Cleaning
A user on WUS (RonD.) recommended Rodico dipped in water as a cleaning method so the dial came off for a cleaning experiment.


The dial is marked as made by Jean Singer & Cie - a rather famous dial making company that is still in operation today.


Mounted on a hand-made aluminum "anvil" that came with a large lot of watch making tools picked up at an auction.


The Before Shot
Icky:

The After Shot
About 25 minutes of careful work with the Rodico, water and q-tips to absorb the water. I'm genuinely impressed with the results and it looks a hell of a lot better: Not perfect, but that's not achievable!

CROWN!
Bless internet sellers of watch parts who take the time to measure, describe and photograph their parts. The correct crown has arrived and fits the stem!


Next Steps

  1. Parts watch: A mostly complete UG 218 movement and dial is on its way to me. Mostly for the NLA and unobtainable pivot shaft for the micro rotor (and I have plans to repurpose the seconds hand for another watch).
  2. Watch maker vacation: Then this watch and the parts watch will go on vacation to learned watchmaker for a full service.
Thanks as always for reading.

Gratuitous green on green on green with UG dial cleaning shot (Kentex Marineman, brilliant and obscure)"

Post 4: Early December, 2025 as combined with Post 5 (Xmas eve, 2025)


This should be the final chapter of this adventure (reserving the right to epilogues and sequels).

First, Cheers! And thanks for giving a **** by reading and commenting, many thanks!

Second, the watch is back from an extended watch vacation. Full service, new mainspring and thanks to Darryl Lesser (Darlor Vintage Watches) for hunting down the correct crystal, after a few attempts. I certainly couldn't find one and had resigned myself to a cracked crystal.


Third, was this "worth" it?

Sure! I had a pile of fun, learned (and continue to learn) about the UG brand and Microtor movements! And from a "did I spend enough to just buy a good one?" perspective, also worth it!

  • I'm into it for about $750 (CAD, all amounts)
    • Acquisition cost (winning bid, gas, snacks) ~= $150
    • Parts (Microtor complete, crown, crystal, band), service and shipping/taxes ~=$600
    • I'm omitting the 2nd parts movement, didn't need it and it'll go for what I paid.
      • Edit - no, it did not.
  • BUT this is offset by the joys of the "dresser top" lot! flogging "what it came with" it and the parts movement (the net in my pocket amounts):
    • Hamilton Skip Jack 505 electric (not working) $150
    • Cuff links and box $35
    • Masonic ephemera $30
    • Seiko quartz $10
    • The vintage Solar with a "parts and repair" AS 1361 (sadly not a Solar Oyster aka store-brand Rolex) netted $66
    • A very lovely gold-plated and purple dialed Seiko ladies watch was running (11-3450) netted $47
    • A pair of Finnish folk art sterling silver cuff links netted $29
  • In addition, I resold the unused UG 218 parts movement in a manner I'd like to think was "better advertised" and netted a $123 gain (I'd expected to break even or loose slightly and didn't count it in the costs).
  • With all this sold (net about $490), the net cost of the watch is about $260.00 for a working and serviced UG Microtor that looks awesome and works great
  • There's a un-serviced version on ebay right now with a cracked crystal that would cost me about $1120 to get to my door, plus a service and crystal. So, ahead on the $ side too!



Finally, I'm searching for a 16mm UG buckle for the band and I'd love to a period ad or catalog showing this watch. The buckle is proving difficult and this great thread on OF saved me from a known ebay faker. If you've got a buckle, get in touch!

Thanks again for reading and commenting. Now get there out and have your own watch adventures!

Thanks for sharing! I wish I had the skills and time to do this.
Thanks!

You 100% have the time and skills for something like this. The most difficult mechanical tasks were either fitting the microtor or removing the dial. In each case, 2 screws! In terms of time, I did this over the course of 6 months as or when time allowed or parts showed up. A professional did the "hard" work of a service.

The beauty of working on watches: 1) don't take much space; 2) you can put them down for as long as you need between steps!

I think that was mentioned in his "sold" list.

Boo. I’ve always liked that line. Shied away because there is minimal maintenance support.

@Dan S is correct, the Skip Jack has "done gone on", and sorry to report to @Larry S (do I need to append an S to my user name?).

Electric balance wheels, of any type, are a super cool "intermediate" technology (I've a had a working Matthay Tissot that went "tick tank") but they require specialist servicing.

Sadly the 505 in the Hamilton was non-running and 1) service costs are high; and 2) the 50s dog leg style watches are lovely but not to my own tastes (I have C Type Connie's, not pie pans).

Pics or it didn't happen:

Great story and project. Congratulations on the outcome and overall deal you got.
Many thanks! The story and learnings are the key parts for me (the deal is a bonus!)
