I'm working towards a project of making watches from scratch, and as part of that I'm considering buying a milling machine. Given the precision levels needed for both milling and boring, I'm considering a rather costly option, the Wabeco F1200. It has a 0.01mm tolerance for milling and 0.03mm for boring.
My question: would you have an opinion or experience with the suitability of such a mill? Or would you have alternative suggestions for me?
I broke the pivot of balance wheel on ETA 2804-2.
I bought a generic complete balance wheel with bridge for ETA 2824-2 (http://www.ebay.com/itm/262234041099?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT) and tried to install it without any difficulty. There is only a difference between the new and old one is the shock assemblies (Incabloc vs Novodiac). In the photo below, the new one is the yeallow on the right hand side.
My question are:
- Is the complete balance wheel and bridge replaceable between those movements?
- If Yes, after installed, the balance wheel has swung a little bit then stop. What is the reason? How to fix it?
Hello everyone, first of all I am fairly new in watch repairing/collecting, so please go easy on me! Recently I have bought an Eternamatic 3000 Wristwatch Automatic Date movement with the calibre number 1500k. I have been looking over the net since forever to find a case in which this movement would fit in. I did some research and came up with the exact "dimensions" of the movement. I am attaching the sheet below.. I know that it is forbidden for other user members to promote the selling of such items, but at least if I can get a recommendation as to where to go on the net for the case that would be great...! Thank you very much everyone!

I hope this is not a silly question but I'd like to identify what tool(s) I might need to open this type of screw back watch case (see pic. below). This is an inexpensive Victorinox Swiss Army watch and I really don't want to spend $20-$25 at a Jeweler's to have the battery replaced. I know it's definitely not a snap/pop off case.
I am wondering if anyone could provide some advice on polishing the scratches off steel watch case and bracelets? Would love to hear how you could do it, both for polished steel and also matte/satin finish steel.
You said it gains about a minute every 24 hours, I see the beat adjustment lever (the one that is bent downward over the back plate) is pushed to one side, this lever will advance or retract the beat therefore speeding the clock up or slowing it down. Also check to see if the balance spring is free in the slot of this lever if not it may be putting too much tension on the spring. Just so you know, the closer the slot end of the lever is to the end of the spring (where the taper pin holds it) the slower the clock will run.
It's very difficult to provide help without pictures. From the information you've provided, I can tell you that Omega pocket watch with movement number 5,694,216 would have been made between 1916 and 1923. The 15 jewels and 2 adjustments would align with these dates as well. I do not know what "Fortune" or the other number mean. Here is a picture of a watch made in the same time period...does your movement look like this?
Hi Andy, The link introduces/defines Thermodynamic which is the study of heat energy conversion to work and vice versa. It is about transformation of energy. One form of energy (heat) transforming into another form ( work) and not concerned with transfer of heat, from hot to cold.
Understanding the nature of heat and the mechanism heat transfers from hot source to cold, is a key len33 is prepared to use. His question shows him ready to absorb the concept.
