Where's the Click?

I'm working on a Waltham 8 Days aircraft clock from WWII. It has dual mainsprings which are wound up. I need to unwind them before going any further but am unable to locate the click. It appears that any further disassembly will affect the drive train. Am I overlooking something obvious?

Some of the older watches would have a leaver on the side near the winding mechanism. You would put some tension on the mainspring while depressing the leaver and then slowly release the mainspring. Need pictures of the side/edge of the movement.

Thanks, jdrichard. That led me to the click. The first photo shows the click which disappears in the second photo as the watch is wound.

No problem. I’m not a pro, but I have a lot of pocket watch repairs under my belt. Old Hippie OH is the pro.

I did make one old Chevi car clock from 3 broken ones. Three layers of plates, and a electro magnetic to energize the mainspring (leaf spring)

Looks like a Waltham CDIA aircraft clock.

I've got one sitting no more than 1 foot from me now waiting for me to clear some other projects before I work on it.

I've got the parts list and a diagram of parts, but its one of the few Waltham aircraft clocks I don't have an exploded diagram of.

I've got a small collection of WWII aircraft clocks and have in the post coming to me my first German aircraft clock.

If these clocks interest you for made in USA Military timepieces I recommend the book 'Military Timepieces' by Marvin E Whitney

Mostly USA, for British Military Timepieces you need funnily enough 'British Military Timepieces' by Konrad Knirim, just be prepared for a price shock as  Whitney's book is not cheap, but Konrad's price is out of this world, but they are the best reference books for British and USA military timepieces, Konrad's is full of great colour photos, whilst Whitney's book is filled with exploded diagrams and service manuals.

      Unusual Seiko dial damage

      Believe the relume (not a fan) was done a long time after the damage.

      A lathe with indexing that won't break the bank?

      By nickelsilver · Posted

      I have a little milling attachment for my WW lathe, but very rarely use it and not for wheel and pinion cutting. For that I use a small Sixis 101 milling machine. I normally do direct dividing, but sometimes have to do an odd count and use the universal index which also fits on the Sixis.   Back in the day when I didn't have a mill, I would cut gearing on my Schaublin 102. It has a universal dividing attachment which fits the back of the spindle. Both it and the one for the Sixis are 60:1 ratio, and with the set of 4  index plates I can do almost any division. When I've had to do a strange high count prime number, I print a disc with the needed division and just place the plunger on the dot. Any position error is reduced by a factor of 60 so still plenty accurate.   The machines are a mess in the pics as I'm in the process of making a batch of barrels for a wristwatch 🙃.   This is the Sixis. The head can also be placed vertically, as can the dividing spindle.   Dividing plates. The smaller ones fit another dividing spindle.   Universal divider for the Sixis. I put it together with parts from an odd Sixis spindle that takes w20 collets, like the Schaublin 102, and a dividing attachment from a Schaublin mill.     The dividing attachment for the 102. The gear fits in place of the handwheel at the back of the headstock.   And the little milling attachment for the WW lathe. I just set it on the slide rest to illustrate the size, you can see from the dust on it it really doesn't get used much. I think only when I change bearing in the head, to kiss the collet head seat (grinding wheel still in the milling attachment).

      Opinions on Seiko's 4R and 6R movement quality from those more able to judge

      By SidKop · Posted

      I read a lot about the quality (or lack thereof) of Seiko's 4R, 6R, 8L  movements...or more specifically the lack of regulation from the factory. Especially when compared to similar priced manufactures using SW200's or ETA's. I thought I'd ask those more in the know, do the 4R's and 6R's deserve their bad reputation, is it fairly easy for someone with minimal skills (or better yet a trained watch mechanic) to dial in these movements to a more acceptable performance.    For background I spent more on a 1861 Speedy years ago, expecting that the advertised 0-15s/d  would probably perform more like 5-7s/d. In reality it's been closed to 2-4s/d.
