The DEN-RO Watch Company, has a long but difficult history to unravel. I spent a lot of time researching this brand to figure out its origins. The DEN-RO Watch Company was founded as the DEN-RO Import Company in the mid 1940s by a Swiss man by the name of Bernard Vuille. This was a high-quality / best value brand that imported expensive Swiss movements produced in Tramelan, Swizerland, and sold under a different name in the United States through several high-end jewelry store chains. This quality is evident by the absurdly accurate timing of the movement as you can see in the images. When I received this watch in a lot, it was not running, and I couldn't adjust the time. It appeared as though someone had previously tried to service it but dislodged the shaft restraint bracket. The case was in decent shape, but very dirty. The movement was sticking, thought it was running. I partially disassembled the movement (bridge, balance, pallet fork, gears), cleaned the parts in an ultrasonic cleaner, demagnetized all the parts individually in pods, reassembled and oiled everything, timed it, and demagnetized it again. The crystal was polished with a multi-stage process using 1000 grit, down to 1500, to 2500, and finally 3000 and finished off with an acrylic polish. I then used UV-activated epoxy glue to seal the crystal to the case to restore water resistance. This DEN-RO now runs exceptionally well and keeps unbelievably spectacular time throughout the day. Can I pat myself on the back here? I've identified that the watch on a time-grapher (after re-assembly) has an error rate of +/- 1 seconds, and gains about 3 seconds in a 24/hr period... which is *exceptional*. My wife tells me that I'm only allowed to keep 12 watches in my case, and all others I have to sell. If there's anything particular you're looking for... I have 100+ watches from various lots that I've purchased, please let me know. Keep in mind, this is only a hobby, and I only get to them when I get to them. This is what I've done to the watch, and what you get:- Original acrylic crystal sanded (1000/1500/2500/3000 grit) and polished, w/ epoxy - Partially disassembled and re-assembled movement for oiling - Oiled all jeweled pivot points w/ 8000/4 oil.- Greased flat-ring gasket (greased) for screw-in case-back - Cleaned / restored original DEN-RO 2-piece watch-strap and buckle- De-magnetized on a watch de-magnetizer- Timed on a timegrapher to within +/- 5 seconds Here is a video on YouTube of the actual watch movement in the watch and running: https://www.youtube.com/watch?v=sET3wKlo768 Note: Prior to a class-action lawsuit in 1963 in the United States, many watch companies used to put "Waterproof" on the watches. This was disingenuous at best as most of these watches were barely able to achieve water resistance of 1 Atmosphere of pressure. After the lawsuit, the use of "Waterproof" was no longer used and most watches put "Water Resistant." So while this watch says "Waterproof" it most certainly is not. I packed grease in the end of the stem/crown, greased the case back seal for improved sealing, and also epoxied the crystal to the case, but I highly recommend you do not use this watch in the water. That said, it's certainly capable of being worn in the rain, or getting splashed. DISCLAIMER: I hate to do this, but I want to make it clear to those who don't know what they're buying. You are buying a vintage watch. While not delicate, these watches should not be opened by people who do not know what they're doing. Most of these watches I'm selling are anywhere between 40-70 years old. Although in most situations I've completely rebuilt the movement, you are not buying a new watch. I only sell watches that are working and keep time. This is not a career for me, I am a software engineer and do this when I'm not working, or renovating my house. This is a hobby of mine. Please do NOT buy a watch if you've never owned a vintage mechanical watch before. Please be mindful of how these style of watches work. Do not over-wind the watch either. You can wind until you begin to feel resistance (usually 10 rotations). Do not continue to wind the watch even after you feel resistance or you will destroy the movement and the main spring, and you will be out of luck. These watches I sell are vintage. I put a lot of effort and personal satisfaction into them because I like taking something old and broken, and giving it a second chance. I generally lose money on each watch when I consider what my time is worth and what I could be making contracting after hours. Please know what you're buying. If you've never owned a mechanical watch, please do some research, or e-mail me. I'm happy to answer ANY questions!
