START YOUR WATCHMAKING JOURNEY WITH THE BRONZE DIVER
The Bronze Diver is our first kit with a bronze case made of a strengthened copper alloy with 8% tin, commonly known as CuSn8. Over time the case will change its colour and develop a beautiful and unique patina. The case is completed by a a unidirectional 120-click bezel with a matte insert, scratch resistant sapphire crystal and a screw down crown to ensure the water resistance of your watch.
The kit features a matte black dial with a depth embossed centre, printed luminous hour markers and a precission scale with minute numerals. Above the dial, polished lume filled diver hands match the colour of the bronze case.
Underneath the dial, the reliable NH-38A automatic watch movement will ensure precise time keeping of your watch. The automatic movement does not require any batteries or manual winding, and is instead powered by the movement of your wrist.
BRONZE CASES - A FEW POINTS TO NOTE
As this is a solid bronze case, please note that when the case arrives it will be of a rose golden colour and develop a patina over time. Please note that a bronze case can cause a skin reaction, if it is in contact over a long period of time. Using a stainless steel case back, greatly reduces the contact to your skin, but if you notice any issues, please stop wearing your watch for a while.
