Esser Watch Case Opener

Although I have not seen one of these I can see how it works. It is for screw back cases. The tabs are for the different  slot sizes in the case back and fit into the part (the bottom right of you picture).Then you turn it over and adjust the distance required then turn the whole unit to undo the case back. I guess the other part is a clamp to hold the watch case if a tight one is being undone.

PS There was one on eBay SOLD & it shows instructions.

    • H Watch Repairers—is there is a ‘standard format’ for the service marks or codes lightly engraved inside cases of pocket watches or wristwatches?   Sometimes I can see there might be a reference to year/ month but other times am confused. I’ve included an image of the rear of a 1951 Hamilton 992B Railroad pocket watch as an example. Thank you for all information you can give, Mike
    • Hi to Blackminou29–am a collector/ caretaker—good luck to you following your repair course—with hindsight I wish I’d pursued a career in both watchmaker/ jeweler fields—good luck with whatever career passion you engage.   Thank you Watchweasol for posting the amazing TZIllustratedGlossary! Best wishes, Mike
    • yes I noticed the new site and I miss the old site. It's the unfortunate problem of the Internet here today gone tomorrow sometimes some of the stuff gets backed up and sometimes well it does not then the problem with the early Seiko's were there were not necessarily designed for distribution across the planet and as such there is no customer support for them. So trying to find early stuff like technical information or sometimes even parts list for older Seiko is is problematic. But I did find you a you tube video. A quick look he seems to take a heck of a lot of time to actually get to the service single I did not watch all that but it does look like he did disassemble or started to say there's a tiny bit here  
    • RichardHarris123: Hello and welcome from Leeds, England.  I have family all over Australia, went as £10 poms Thanks Richard. Hope you’re able to visit your family here and that they’ve all done well 🙂 My relatives arrived from England in the 1790s transported on the ‘Second & Third Fleets’—a story of timber sailing ships, of convicts and doing well in this huge Country of Australia. When I visited the UK in the 1980s, I was too young to comprehend the depth and breadth of its history…  Best wishes, Mike William Chapman, my 4th great Grandad’s charges, at age 23 read at the Old Bailey; sentenced to 7 years of transportation to Sydney.
    • The whole process and the progress are closely observed, it's hand-driven and very controlled. I can't see the "danger", unless you are watching the TV while doing it. As you could have read, and in this quote "wheel" is the balance-wheel.
