British military 1917 evaluation wristwatch

This popped up on ebay last week as a £50.00 buy it now

During the Great war the British military had been issuing pocket watches to serving personnel and hadn't supplied wristwatches, these where instead bought mainly by officers privately for use at the front lines with wristwatches improving and the introduction of the water resistant cases, unbreakable crystals and radium dials the Trench watch was born and became an item of necessity for serving personnel.

It wasn't until 1917 that the war department purchased the first batches of wristwatches supplied in two forms the first being a classic trench watch of water resistant case, black dial with radium numerals and unbreakable crystal and the second type being a large cased snap back, black dial with radium numerals all had 15 jewel Swiss movements. These watches where purchased for the purpose of evaluation to assess the usefulness of issuing wristwatches to serving personnel.

This watch is of the snap back type and has a unusually large for the period 38mm  case made of nickle, the dial is  black enamel with radium numerals.

All the snap back models have issue numbers that follow the same form a five digit number beginning with a nine followed by a letter M there is also a Broad arrow mark or Pheon crudely stamped on to the back some watches are stamped with two broad arrow marks that touch at the tip this is thought to indicate that the watch had been withdraw from service.

The movement in these large snap back models is the same in all known watches where as in the water resistant 1917 watches there is some variation. The movement is a good quality 15 jewel movement and no one has yet been able to identify who manufactured them there are no identifying marks but there is a brevet patent number on the dial side so it may be possible to trace that and establish who made the movements.

No one is sure what branch of the armed forces these snap back watches where issued to but it cant have been to front line personnel because having no water resistance would have rendered them pretty useless in the field, many have speculated that they could have been issued to the flying corps because the design mirrors quite closely the pocket watches already issued to them at the time, these snap back models where only issued in 1917 and withdraw from service shortly after, but the water resistant watch became a regular issue watch there after IMG_2628.thumb.JPG.351ef07a95fe2f8794a765e1b85db90d.JPG

It is however an interesting footnote in the development of the military wristwatch and is amongst the  first officially issued and stamped British military watches of the Great War.

Wis, I think it may be an Electa movement

 I will have to search through my movement catalogues and see if I can get a dial side match on the setting lever bridge I've already tried Bestfit and found no match I shall try and look for a dial side photo of some Gallet Electra movements that will tell me for sure as there are some similarities on the bridges.

Have you got the patent number, I can look it up?

Thanks. Carl.

Also, the watch below has what I am sure is a smaller version of the same movement:

This movement is a Fontainemelon but I would have thought if the mystery movement was one it might have been identified. There are so many similarities though I would go with Fontainemelon if I had to choose.

I've done a comparison. If you ignore the bridges and plates and look at the screw, pivot and wheel placement from the FHF to the left and then compare to the finish of the wheels and the movement of the FHF to the right it looks like a match to me.

A picture of the dial side would clinch it.

    • Yeah, I saw that in the tech sheet but I don't see how it can be adequately cleaned with the friction pinion still in place. I've accidentally pulled the arbor right out of the wheel once when I used a presto tool to try and remove it. Mark shows how he does it with the Platax tool. Those are a little too pricey for me so I got one of these from Aliexpress and I just push down on the arbor with the end of my brass tweezers. That usually gets it most of the way out and then I just grab the wheel with one hand the and the friction pinion with the other and gently rotate them until it pops off. Probably not the best way but it's seemed to work for me so far.    
    • Thanks, Jon Sounds like a plan. Obviously I'll have the face on so do you think gripping with the holder will create any problems, but I will check in the morning to see how feasible it is but I assume it only needs to be lightly held. As for holding the movement instead of the holder won't be possible in this scenario as one hand will be puling on the stem while the other pushes the spring down. That was my initial concern is how the hell can I do this with only one pair of hands. All the other times I've had to remove the stem hasn't been a problem, apart from the force required to release the stem from the setting lever, but now I need to fit the face and hands its sent me into panic mode. If it had the screw type release things would be a lot simpler but that's life 😀       
    • Hi Jon, do You think that relation spring torque - amplitude is linear? I would rather guess that the amplitude should be proportional to the square of the torque. I had once idea to check it, but still haven't.
    • I did not. I thought about it, but I had cleaned it in my ultrasonic, and the tech sheet shows lubricating it in place already assembled, so I figured discretion was the better part of valor. Although since I have to depth the jewels anyway, maybe I pull the pinion off to rule it out 100% as part of the problem. Do you know if there's a safe way to do it? I don't want to use a puller because it would push down on the plane of the wheel, and that seems like a Bad Idea. I thought about using a roller table remover, but I don't think I have a hole stake pointy enough to push it down.
    • Before putting it back in the case I would fit the hands and use a pin vice on the stem to make sure the hands were in line.
