Hi all, I'm going to be refinishing this old Seiko Lord Matic when it arrives. The metalwork is fairly easy BUT I've never tackled a faceted glass crystal. As it is almost impossible to locate a NOS one, I want to try to polish out some of the lighter scratches. How do I go about doing this? Products, techniques etc Thanks Robbie Sent from my Honor 5c

Hi. I worked in Rolex dealers a couple of decades and got a bit bored with repair. I decided I wanted to either make watches or teach watchmaking. I attended WOSTEP Refresher Course in Switzerland in 2004 and received the diploma. During this time, my wife did not want to remain in the States, so went to work for the U.S. Army in Heidelberg, Germany. We continued to live in Germany for 9 years and now 3 in S. Korea. I spent a lot of time finding and buying used tools, rebuilding tools, and making tools from scratch. I also spent a lot of time learning hand finishing of parts. Now I spend most of my time in Christian ministry (which is what I started out doing). I am writing a book and I give a couple of different seminars to chapels and churches. I still work some on finishing up my first watch, a pocket watch whose case is jade. I am nearly through making a machine for cutting inside curves in jade and other stones for a more comfortable wristwatch and have a couple of unique designs.

The correct lubricant for any rubber seals is silicon grease. It's very cheap on eBay Sent from my iPhone using Tapatalk

Here is the spec. sheet for the Hattori Y121M movement....This will help you figure out if the movement is compatible with the one currently in the watch: http://www.jewelerssupplies.com/HATTORI-Y121.html Joe

Stainless steel rusts quite readily when in contact with mild steel and moisture. I doubt if that has happened here but stainless is not as resistant to chemical attack as you might think. Cheers Neil

Bienvenue! If it's just stained, try a toothbrush with warm soapy water. If that doesn't work, my personal favorite cleaner is a car polish (the very fine kind). It's also really cheap. For parts, I love ottofrei because they have a gigantic inventory. For you in France, try cousinuk, the shipping might be cheaper and they also have a lot of stuff. Their website is also easy to search (create an account, it's free).
