▼ Seiko SEIKO Sports Scuba Master 200m Titanium 7K52-6A00 Date Quartz ▼ Serial number: 550243 ▼ This is the Scuba Master model, released around 1995. It was considered the most expensive product in the catalog at the time, making it an excellent model. It boasts high-spec features, including 200m water resistance, a unidirectional rotating bezel, a screw-down crown, and a fully automatic diving function. ▼ It has hour, minute, dive time, depth, and maximum depth hands, a 1/10m hand in the 12 o'clock subdial, a dive start time/alarm hand in the 6 o'clock subdial, and a permanent seconds hand at the 9 o'clock position. The indexes and hands are luminous for high visibility, and of course, they glow brightly in the dark, making them very practical. A calendar indicating the date is located between the 4 and 5 o'clock positions. ▼ Please check the condition in the photos. If you leave a comment, I will provide guidance within the scope of my knowledge. ▼ Unfortunately, the battery is dead. When using it, please have the battery replaced at a specialist store, and if you intend to use it for diving, please have it waterproof tested by the manufacturer or a specialist organization.
