Hi, 

Just picked up this mystery watch from a local charity shop. Any thoughts?

All I know is the hallmark is for the Glasgow assay office dated 1916. The JW sponsors mark is a mystery and going to be a tough one to solve as the Glasgow office shut down in 1964 and the records have been lost.

This watch is also 80 times more radioactive than any other I've measured. Would love to have seen it glowing when new.

All the best

Alec

Lovely looking movement. It would be good to see under the dial and get a movement diameter to help identify it. Any marks under the balance?

I can feel it glowing from here 🤣   That's a lot of radium. The first thing I do with a radium watch is (wearing a mask) seal the dial and hands in a plastic bag. It looks to be a nice enamel dial, so removing the radium in water should be easy.

Hi Mike, I was just about to attempt a cheeky peek under the balance when I thought "let's check the dial for radium" and all works stopped for now.  

The movement is 27.8mm(ish) trying to measure it still cased.

The lume is missing from the hands, imagine the reading when it was intact.  

What type of mask do you wear, @mikepilk ?

I use the N95 masks I bought in lockdown.
I cover the desk in clingfilm to prevent contamination, and wear latex gloves (maybe not necessary). I remove the radium with cotton wool buds and warm water. Everything I use which comes in to possible contact with radium, I seal in plastic bags and put in the household waste. The small amount of cleaning water, I soak in to kitchen paper and bag. I think it's OK to tip in down the drain (here in the UK).

There are plenty of opinions on just how dangerous radium is. The bottom line is you don't want it in your body. Taking the above steps is not difficult and should prevent a chance of ingestion of particles. Once under water, there's no chance of inhaling particles.

With some 'historic' watches some people prefer to leave the radium intact for authenticity. Painting a clear lacquer (nail varnish) over the radium will prevent particles flaking off. 

I have a 1940s Universal Geneve with a radium dial where it's not easy to remove the radium, and it looks better left original. I keep it sealed in plastic bag to (hopefully) keep the radon gas in.

Out of interest, do you have a reading in of the radiation count?

There are two issues with radium dials. First the possible ingestion of radium. Secondly, when the radium atom emits an alpha particle it becomes a radon gas atom.

There are some internet experts who'll confidently assert that it's not a problem, but I'm going with the actual experts on this one and following something along the lines of Mike's regime.

I have done a far amount of reading on radium dials etc and I have have a  good base understanding of radioactive decay. I think that wearing gloves and a mask is adequate and your exposure time will be limited.  However I know some people are wary of working with radium.

Newbie guess - could it be a Wakmman - correct time frame, I have a small Swiss Walkman pocket watch with similar hands and radium issues. Incase you don't already have this info; 

In 1895, Mr. Wakmann was born in Russia with Jewish origins. 

1943 – During WWII

In the early stages of World War II (WWII), Mr. Wakmann started his watch business in Portugaland and had been representing several high-end European watch brands.  At the same time, warfare was spreading across Europe at a rapid pace.  During the Holocaust, the Wakmann family devoted great efforts in assisting refugees from the Nazi horror.

During WWII in North America, many American watch companies were put at a disadvantage.  Their production was switched to war products, while the Swiss watch manufacturers produced watches for war efforts and civilians.  As a result, the U.S.government decided to support the American watch industry.  The Swiss Watch Import Act was subsequently formed, and the U.S. Department of Commerce started to impose custom duties on high-end imported Swiss watches. 

Mr. Wakmann quickly recognized that this was an excellent opportunity to start his professional watch business in America.  Therefore, he travelled across the Atlantic Ocean, from Lisbon,Portugal toNew York City, with the aim of establishing his new business in North America– to fulfill his lifelong dream.

If not looking forward to seeing what it was all the best...Jules

 

Not Walkman - Wakmman! Spell checker again...

Interesting experiment. 

There are a lot of components in modern engine oils, some of which may not be suitable for watch movements?

The case at least is from 1916 so before Wakmman existence.  The style of hands and radium dial are quite common.  If there's no makers mark under the balance or dial then using the best fit catalogue is the next step.

I've never heard of Wakmann, sounds Interesting.

27.8mm makes it about 12.5'''

There's no Wakmann in Ranfft, but in Bestfit for Wakmann it says "See Breitling".  Under Breitling there are no matching movements of that size. Identifying from the keyless would be best.

We have a bit of a problem with radium lume here in Scotland in the Firth of Forth. Apparently the MOD decided to dump aircraft instruments in the river after WW2 and the stuff gets washed up on the beach and gets collected when detected. It’s costing millions to do this year after year.

the most recent write up I can find is here

https://inews.co.uk/news/environment/dalgety-bay-radioactive-scottish-beach-almost-safe-33-years-2299839

They are collecting fragments around 1mm square which are considered dangerous apparently.

You would probably have needed sunglasses because the brightness Would blind you.

You do realize the planet is a really big place. Then typical government military agencies the philosophy is out of sight out of mind don't worry about it ever again. So unfortunately for all of us  these problems are ongoing for the entire planet.

 

Oh give Scotland  how about  recycling is an example of a product that got recycled  into something interesting.. Don't worry you'll figure out really fast he gets really  excited about it. Yes something to keep you warm on a cold night  perhaps carried in your pocket although it does get a little bit on the warm side.

@JohnR725 he must have done that for April fools day! Having served in the British army there is no Scottish army, only Scottish divisions. I would have loved that ration pack whilst serving. 😂

Interesting I never questioned whether is valid or not. I did find it was rather interesting and I really did like the heater. Now I feel sad because I thought the heater was interesting idea.

Don’t think it’s a spoof. If was the disarray among the Scots regiments caused by the sinking of Iron Bru tanker, HMS Sauchiehall, that led to Dunkirk.

    • Excellent info, thank you! So when you say "conforms to the standard" does that mean, for example, that parts are interchangeable between brands and ages, or that you could use accessories built for that 110-year old one on a newer one that was built in the 1990s? Also, thank you for taking the time to answer my questions and your patience.
    • It was first a brand, but became a standardized style. So you will find some older lathes actually marked "Webster Whitcomb" and many other makers who built WW lathes conforming to the same dimensions for spindle height, bed shape, attachment setup, collet size and design. https://www.lathes.co.uk/derbyshire/ So when someone mentions a WW lathe today, they are talking about any lathe that conforms to the standard, which could be a 110 year old American made lathe or a European made lathe from the 1960s or something else.
    • Hi guys, just a little thank you for the CLOCKBARN site in America.  I purchased a TIMETRAX APMLIFIER to help with setting clocks in beat from CLOCKBARN it arrived on time and when tested worked ok.  A week later I had occasion to need it again, this time nothing the unit was dead. Checked out batteries , probes etc , nothing.    I messaged CLOCKBARN  to this effect.  I got a prompt reply that he would send a replacement which duly arrived today and having tested it it’s ok.  So I can recommend the site should you need to use it. The person,persons who run it are genuine guys.  So thank you CLOCKBARN  for your excellent service.
    • Hi there! You have learned how professional watchmakers feel about Timex. It is very difficult to find one willing to work on them, for a few reasons: 1) a lot of them wrongly believe Timex cannot be serviced, are riveted together. This is a myth. 2) when serviced, they still cannot meet the performance standards of jeweled mechanical watches (-20sec/day is good enough for a Timex) 3) customers are unwilling to pay the watchmaker's hourly bench rates because the watches are worth very little The service manual for the M33 is available at https://heritage1854.com/m33 but you also need the M32 and M31 manuals because they build on each other (31 is the base, 32 has date, 33 has day and date) https://heritage1854.com/m31 https://heritage1854.com/m32 A stuck date changeover can be due to a missing, bent or broken detent spring (part 2576 in the manual) or the date wheel (2556) got stuck or separated from its post, or maybe disengaged from the hour wheel. With a little confidence, these are not difficult to repair and parts are pretty much interchangeable with any other Timex from the same era having the same features. So it is very easy to find inexpensive spares in the form of junk watches (don't bother trying to search for individual spare parts). My recommendation would be to find a junk Timex with an M25 (older manual wind with date) and practice a little with it. Follow the service manual from the same website. The automatics are a bit more difficult to work on but once you get a feel for how they fit together, you can make an attempt at your automatic and you would be able to use many spare parts from the M25 if necessary. To work with most Timex movements, you do not need a lot of tools. Just one screwdriver, 1.4mm is a good size, tweezers, and hand levers to remove the hands plus hand pusher tools to replace them. Of course if you want to do a full cleaning and restoration more is needed. But to get it apart and diagnose, only minimal tools.
    • I do indeed have some programming and electronics know-how. 3 decades writing code for a living, and playing with microcontrollers as a hobby. 🙂 It helps with my actual living of being a voice actor because I can maintain my own equipment- no one around to replace the caps or the tube in an obscure botique mic that isn't made or supported any longer. Also saves money maintaining and cleaning my own interfaces and mixers when they develop problems in the faders and such. That said... I do have a question that, I'm sure, will betray my ignorance about certain areas that I have yet to fill in. I understand a "WW" lathe is a "Webster Whitcomb", but from what I understand that is a style of lathe and not a brand, correct? If someone would be willing to clarify and maybe expand on the terminology, it would be helpful so I can better understand the advice being given and know what I need to look into to further my knowledge. For example, a Sherline mill would appear to be either a separate piece of gear or an attachment/expansion to their smaller lathe. When you say you have a WW lathe and a sherline mill, can you say exactly what devices you have? Thank you! (I just realized I have a few Raspberry Pis and some Arduinos of various form factors around here I could probably put to good use in a scenario like you describe above).
