Hello, I could not fint any answer to this on any other thread.
Im using Isopropyl alcohol for the last step of hand cleaning movements. However i can not find a good way to throw used liquid away. How do you do it, I know that the liquid will turn into gas eventually however since i fill a small jar there is always going to come times when i need to throw it away. Where do i throw it?
How do you do it?
Thanks in advance, Jakob
Hi to you all,
I was wondering, if you use a regular ultrasonic instead of a watch cleaning machine. How would you rinse your parts? And how many times? In which solutions?
I always cleaned my parts in the ultra sonic with a solution and rinsed the parts in benzine( that's the way an old watchmaker learned me) but i've found out that very often this does not give me the results i was hoping for. Can I perhaps get little jars with a rinse solution and run those in the ultra sonic?
I'm a newby, so please be gentle! I have an early Accutron into which I need to fit a new crystal. I have a NOS crystal. I understand the principle of fitting a tension ring crystal with a press, but need to make a die to fit the crystal. Does anyone know (or can estimate) the optimum internal angle of the top die please?
Secondly, on a slightly different subject, I have seen on this site discussions about recessed crystals and non-recessed crystal, but from what has been said I still don't really understand the difference. Could someone enlighten me further please?
Thanks in anticipation.
I have managed to get hold of a singing bird cage at a reasonable price after years of trying.
It's not working...I would like some advice on what solutions to use to clean it as I think it just requires a good clean, nothings broken.
Can anyone tell me what make of cleaner to use and what lubricant would be best, have attached photo's!
My experience with the handheld cheap Chinese glass presses on eBay is truly poor, and I've come to learn that I'm not alone. Yesterday I was struggling with it for over 30 minutes to fit an armoured glass in a Vostok Amphibian before giving up. At that point, while still holding it in my hand looking at it with disdain, I thought: "What a piece of utter rubbish!".
Anyway, what I'd really want would be a Robus press, but gosh, that would be over £500 with the die set (tax included, excluding shipping)! So, I found this tool "Professional spindle press for housings and glasses with twenty-four inserts" on eBay for £72. It sure sounds promising, but it would be great with a review, or if none can be had your opinion.
Sharpening is a science and an industry. Trivia facts follow
An important figure in drill sharpening is Joseph Mazoff, a self-taught American. His article is still current on the matter and the basis for most sharpeners, I have attached it here.
A 1st brand drill bit sharpener can cost €600 https://www.wabeco-remscheid.de/catalog/product/view/id/6710/s/spiralbohrer-schleifmaschine/category/487/

If you have something that cuts there is a professional way to sharpen it. Blunt axe? No problem https://www.sharpening.org.uk/product/tormek-sva-170-axe-grinding-jig/
I'm currently disputing an Amazon seller that sent a cheap knife sharpener instead of a 75mm grinding wheel
A relic of the Jewel Wars, this 35mm 1950s Mount Royal with an 80 jewels (kind of) Felsa 4002, 21 of which are broadly functional and 59 which, er, aren’t. I’ve no idea how many of these watches survive today or, indeed, were ever made but it “coulda been a contender” until the likes of Waltham, Orient, and Titoni climbed into the ring with their 100 (and more) jewelled efforts.
Of the two recorded makers of a Mount Royal brand, Choisi seems to be the most likely candidate for today’s curiosity, it being a product of the original company founded in 1929 before its demise, date unknown. The company name was seemingly reactivated in 2013 by a Singapore-owned enterprise which, from what I can see, is largely producing retro-style watches along with homages based on the old company’s vintage models.
