We offer new to market and arguably unique wristwatch cases to make marriage watches using antique pocket watch movements with contemporary wristwatch cases. In addition to the standard. Stainless-steel grade 316 L. Top and bottom glazed with mineral glass. We have designed and created cases with screw-able bottom frames to make it easier to open and reach the mechanism for maintenance or repair. This replaces the more common press closing frames which often require a clamping tool and frequently results in broken glass. With easy unscrewing of the bottom frame any enthusiast can fine-tune the accuracy of their watch by simply adjusting the hair spring regulator, without the need to go to a watchmaker. Both crystals are glued to the bezel and to the bottom frame, which gives better water resistance. We offer 3 types of cases, two of which are beautifully engraved. Diameter: 47.50 mm. Length including lugs: 70 mm. Thickness: 17.50 mm. Strap: 22.00 mm. The cases are ideal for Hebdomas and Hedomas style pocket watch movements as well as Alpine, JWC Kal. 52 and 53, Longines, Moser, Omega, Tavannes, System Glashütte, etc. Please see our other offers. The watches pictured are samples of how the cases might be used and are not for sale. We also offer an assembling and mechanism restoration service by the top Polish Master Watchmaker. We can make up a watch using our own range of antique mechanisms or from one provided by you.
