The box is made of rosewood, has a raised circular top section with holes, a perspex flap with swivel catch covering a circular metal I think tin insert with a hole in it and appears fixed in place. Remains of instructions say, "Close lid so that hole in spring goes --------pinion?" That's the most I can decifer, it was amoungst a deceased watchmakers tools. What is it and how do you use it?

Absolutely no idea but the perspex lid looks out of place. I don't think plastics existed when the box was made.

The last line in the instructions looks like "Movement ------- test".

So could this be some early test tool? Maybe it's some acoustic amplifier for listening to the ticking of the movement. You put the movement in the hole and close the lid and listen from the speaker-like holes.

I don't know. Just shooting in the dark.

That is a very good suggestion indeed it could well be an amplifier especially now I have removed the tin disc. As you can see from the pictures the disc was soldered to the nut. Before further disassembly as it's distructive any further ideas would be appreciated. But I have a feeling Hector may have it.

Ok having no choice and bearing in mind its made of wood so easily repaired, I broke it open through the top. And low and behold it has a tin vibration plate that connects to the tin disk, or did until I broke the solder join. So Hector you are right it's a form of amplifier intended to amplify the sound of movements. What an interesting peice of kit, now I will put it all back together and have a play. 🙂IMG_20230401_133053.thumb.jpg.040410f822b0ffdc46bb9ed429ee46a5.jpg

That is cool! 

I wonder, if when it was made did it have a thin piece of wood where the plastic is now?  Maybe that was just added later when the wood door broke.

It sort of reminds me of the little things they had for the telegraph operators that allowed the sound to be concentrated a little more to ease them hearing it (telegraph sounder box).  Although, I think the way those telegraph sounder box was also to direct the sound more to the person working the telegraph and to be less distracting when there were multiple telegraph machines in a room.

    • This is not rare at all, the dial code and case code don't usually match.
    • Good question!! Anyone know of a substitute movement??!! 🤔🙏
    • Interesting issue that I just noticed: this Seiko 5actus Watch from 1977 has a calibre listing on the dial of 7019-8030R but on the case back it says 7019-8010!! Like a mis-printed coin, is this watch therefore worth a lot of money for its rarity?? 🤪😲🤔🤪
    • I wish that was the case. The Aegler movements used in the early days by Wilsdorf & Davis (for brands like Rolex and Rolco) came in several sizes and without designated calibre numbers that survive.  They become a bit easier to identify during the 1920s. Below is an Aegler-Rebberg, 25.74mm in diameter. It’s from a woman’s Rolex wristwatch. Stamped Rebberg and 500 on the dial plate (but it isn’t a Rebberg 500, it’s the wrong size).  I’d be interested if anyone can identify the movement.  It is based off the Aegler Nr.1, circa 1903, but they based many many calibres of different sizes on it. The closest I have to a positive ID is the  ‘Rolex Nr.50’ circa 1917, but no dial side images or movement sizes are available in the references. There are identical looking movements in many sizes.  The 25.74mm of this movement is a particularly strange size for the era, it equates to 11.41 lignes.      Best Regards, Mark
    • It looks like this movement comes with a number of different shock settings. Emmywatch shows that it comes in versions with no shock settings, 'Incabloc', 'shock resist', and 'Supershock'. Perhaps the different settings position the impulse jewel/roller table in a non-ideal position relative to the pallet fork/guard pin. Are you able to check under high magnification if the pallet fork and roller table are able to operate without any interference? Just for fun I took a look and I have one FHF 70 in my collection, a West End Secundus with a non-shock protected FHF70. I had a note with the watch that said, "Movement is stamped 'FHF 70', but the FHF70 looks to have sub-seconds instead of center seconds movement (??)" but that a google search turned up both types for this movement. EDIT: I just took a look in my parts drawer and I have a few of these movements, both in center seconds and sweep seconds, but they all are non-shock protected.
