Okay guys, I've got something special for you... vintage, genuine Omega watchmaking tools only rarely come up for sale, and when they do, it's usually from parted out sets. In the red, Omega boxes, you have a partial set of the Omega Unicoc Crystal Inserting and Removing tools. The box on the left has a sticker on it that says " Vigor Omega Unicoc Extractory Swiss RM-700." These are the tools that watchmakers use to remove the compression fit Hesalite and acrylic crystals, particularly helpful on the old Sea Master unibody case designs where you can't gain access to the movement except by removing the crystals. You can certainly remove these and other vintage crystals safely using a generic tool, but if you're looking for that special something to add to your Omega collection, and you want to guarantee yourself the absolute safest way to change what can be quite expensive, signed Omega crystals (other than paying your watchmaker to do it, of course), this is what you need! Once you have the existing crystal removed, you'll want to carefully measure the bezel (a micrometer is helpful, and there are tutorials on the web). Then you can source your own original Omega crystals from eBay and Ofrei, etc. When the replacement comes, you can use another set of tools, a crystal press to install the crystal (some of the plastic pieces in the pile at the bottom left are for your crystal press; others are bezel tools for the Constellation). If you don't have an expensive crystal press, I have gotten great results simply using the same tool to re-install the crystal. You'll want to set it on a flat surface and carefully tighten down the screw on the crystal tool. This compresses the crystal ever so slightly so that it can clear the bezel. You position the crystal in place (rotating it to position the floating Omega logo the correct way, if your a stickler), and loosen the screw on the tool. With the tension gone, the crystal pops back out to its normal dimensions and creates a secure, friction or compression fit. Before sapphire crystals, this is the same principal that was used even on waterproof diving watches. So onto the tools... This listing is for one of the three individual crystal tools on the bottom right of the picture. From left to right: 1. 107/3295 - This could be cleaned up to look better, but it will work great just the same. The previous owner wrote "Downtown 01" in sharpie on the tool. 2. 107/3295- Good cosmetic condition 3. 105/3095- The red plastic has a kind of clouded/gray coating. It might clean up, or might just be how the red color ages. The first number is the Omega Part number. The second number corresponds to the diameter of its corresponding crystal. So the 107/3295 is for crystals that are 32.95mm. The 105/3095 is for crystals that are 30.95mm. The tools themselves have obviously been used, but are in good, working condition. The plastic is nice and sturdy. The screws tighten down well. These vintage tools were incredibly well made. These consistently sell individually on the Bay for between $50 and $75 for the mens sizes and around $25-50 for the womens sizes. Price: $70 net to me for either of the 107/3295 tools. $50 net to me for the 105/3095 tool. Check or wire preferred (references available), though if Paypal is your thing, that's fine too. I'll ship it for free in the USA. International is great too, just contact me for a shipping quote. Returns: I'd really like to say "no returns accepted" because I'd like to avoid someone ordering these, changing their crystal and then returning it. But we're all gentlemen around here, so if you get your tool(s) and they don't work for, I will accept returns if you contact me within 3 days of receiving it. You pay return shipping, and when I receive the item in the same condition, I'll offer you a full refund less my shipping costs and any fees incurred on my end. Please use your discretion here. The two pictures below are representative only. I think the pictures are actually from one of the ones out of the sets that I have listed separately.
