I purchased this from Mercari this spring. I am listing it without ever wearing it. The following is the previous owner's comment, please refer to it. ♢ MWC Military Watch Company Quartz Serial ☆ This is a now-discontinued self-winding power generation model from Military Watch Company. It uses Seiko's Kinetic movement, and MWC calls it a hybrid model. Operation has been confirmed. There is some scratching on the crystal, but it does not impair visibility. It's lightweight and strong, with a titanium case that is resistant to corrosion, a simple military-inspired dial design, and a NATO strap – it's cute. Like an automatic watch, the movement moves with a "shaka-shaka" sound when you move your arm, generating and storing electricity internally, and its operation is a step-motion ticking, which is an interesting gimmick. The current hybrid models have hands that move smoothly, like an automatic watch. I believe this is the model that corresponds to the current G10. Tritium self-luminous luminous paint. It's an antique-style watch with a hybrid movement, a discontinued model that is no longer available. The previous owner has informed me that the Kinetic-specific battery has been replaced. I am also open to price negotiations. Thank you.
