Hi folks, I have been lurking here for a while and realise it is time to introduce myself.   As an engineer I have always marvelled at the manufacture and maintenance of such small mechanisms.  I have acquired a watch movement that is possibly from an Ingersoll but it does not have any clues that I can see to be certain.  I assume it is pretty basic so a good candidate I think to try and get it to run again.

Welcome! The red jewels would make me want to look really close at the balance jewels (make sure they're there). Even if they are there, that style cap jewel can be a PITA. You have to access screws from the underside of the balance cock through the hairspring without borking it. (Voice of experience.)

Might also be on the small side for a first attempt. Not saying it's impossible, but getting the balance and hairspring under that center wheel can be a real challenge. Another great way to borkulate a hairspring up good. (Voice of embarrassingly more experience.)

If you're looking for an inexpensive place to get started, check out the 404 club thread.

Many thanks Watchweasol for the reading matter - just what I needed.

In reply to Spectre6000, a trick of the light makes it look as if the jewel for the balance staff is missing, it is in fact there (I just checked) so no borkulating there hopefully.  I bought 4 watches for the princely sum of £8 total so I qualify for the 404 club.   One was a mechanical fashion watch and looks almost un-worn.  I wound it up and it runs, not taken the back off yet to see what is inside.

You still have to get to those screws between the hairspring and the bottom of the balance cock to clean and lubricate the balance jewel setting; borkulation risk is still very present. Just a heads up. Everyone borks a hairspring or twenty when they're getting started (and after they've been at it for a while). Deborkulation is possible, but I've yet to succeed without a stereomicroscope. I've yet to fully and properly deborkulate a hairspring [i]with[/i] a stereomicroscope either. I finally have one sitting on my desk, just haven't had a chance to stretch it out. The first deborkulation test subject is in a drawer awaiting its fate.

Depending on what's in the fashion watch, it may be a better place to start if you want to increase your odds and decrease the cost of success (likely a lower grade movement that's less likely to be missed). It will likely have a more modern shock setting that is easier to work with, as well as larger parts.

Post your 404 score in the club thread! We need pics!

      I'm going to be setting up a decent little workshop here at home.

      By Michael1962 · Posted

      Well I put the spa on Gumtree (selling service) to try and sell it as it only needs a recirc pump to get it going. However, it weighs circa 250kg, so there's 4 fairly strong guys, and I would have to remove the sliding door in the room completely to be able to get it out, as well as clearing out a multitude of potted plants and the Alfresco outdoor setting to be able to get it out. Then move nearly everything in the back of the garage to be able to push it through to the front of the house. I would also need to hire furniture skates to be able to shift it around as carrying it is out of the question. Then someone would need a trailer to get it to their place as you won't get it on the back of a ute. So, the only answer is, out with the reciprocating saw and cut it all up into manageable pieces. Crying shame as it is in really good nick. I was only asking $1,500 and only got two bites, but it would only take something to go wrong with removing the sliding door etc that everything I make on the sale could go out the door on repairs etc. It would have been nice to be able to turn it into tools etc, but que sera sera. I don't know about the rest of the world, but there just seems to be very little interest from people wanting to buy things secondhand.

      I would like to see the movement. The watch is the movement. Anyone can print a name on a dial and sell it as "the maker".

      What are these Seitz B-Jewels?

      By VWatchie · Posted

      Thanks for your answers! There seems to be a contradiction between these two answers, so perhaps I need to clarify. The flat and convex jewels look identical on the side facing away from the pivot shoulder. That is, there is an oil reservoir. I don't know if that changes anything but I thought it was safest to clarify since I didn't include a picture of the jewels from the opposite side.

      unfortunately paying attention to details bumps up the cost. Which is why they shortchange on manufacturing steps if they can.

      Introduction

      By oldhippy · Posted

      Thank you for your introduction and welcome to this friendly forum. We all look forward to your contributions and continued involvement.  When it comes to tools buy the best you can afford a good set of watch makers screwdrivers if you look after them will last you a life time. I recommend Dumont tweezers Number 3 and number 5 for fine work, you can build up from there. You will need different strength eye glasses. Some now like to work using a microscope. Pliers the box jointed ones are best they don't go out of line.
