Thank you for viewing. SEIKO Prospex SNJ033, offered for sale to organize my collection. This is a Seiko diver's watch, a representative model, featuring the distinctive outer shroud known as the "Tuna Can." It was not sold domestically in Japan, but was mainly sold overseas as a 40th-anniversary model. This model is equipped with a solar battery, and the mechanism allows it to function for about 10 years without problems if exposed to sunlight. Functionally, it is a multi-functional model with a digital display, and I think it can be used in a different way even for those who are waiting for an analog diver's watch. Power save function Stopwatch function (1/100 second measurement, 99 hours 59 minutes 59 seconds) Alarm function (daily alarm) Full auto calendar function (until December 31, 2100) Battery life warning function LED light function Diving log function Water depth measurement function Lumibrite (hands, indexes, bezel) Magnetic resistance Unidirectional rotating bezel Screw-down crown Double-locking clasp Screw back Average monthly difference ±15 seconds Approximately 12 months of operation when fully charged After purchase, it was stored in a dark place, so I am listing it as "new and unused," but please understand that it is a personally stored item before purchasing. Recently, there has been an increase in purchases from overly sensitive individuals. When a purchase is confirmed, it will be considered that you have understood the above, and we will not accept any returns, exchanges, or refunds after the item arrives, so please understand this in advance. (Including the perspective of preventing the replacement of the machine)
