Seiko 48 King Quartz. Overhauled by me in April of this year (disassembly, cleaning, oiling), and the battery has been replaced. The coil has also been replaced with a good quality one. Operation: Date quick-set with the crown pulled out one step, and time adjustment with the crown pulled out two steps. Being quartz, there is almost no time deviation. The appearance is subjective, so please check the images. Please ask any questions in the comments. Original crown and belt (KQ mark) included. The free-type belt should fit most people. Although it is an old wristwatch, it is in a condition that can be used daily if you avoid moisture and shocks.
