Approx. 62mm diameter, approx. 162g, extremely rare tulas silver housing, spindle movement with minute repetition and date, on the side skeletonized, enamelling, special steel pointer, signed J. Rejha Praha, walkable, cleaning recommended, absolute rarity. The Tula case decoration was only "modern" around 1900 and was frequently used. Spindle watches around 1800 to 1820 with such housings are sensationally rare!
