Bronze Big MM diving watch

The style is based on Seiko's classic diving watch "Big MM", and the one-piece case has no bottom cover structure. This time, our material is tin bronze CUSN8 material, which will become retro with use. The hands, dial hour markers and chronograph lap luminous are all toned in a retro color. The tin bronze head is specially made to match the case and strap, and the connection is seamless.
