The HEROIC18 M8100 is a gorgeous watch with a reliable automatic, Japanese Miyota 90S5 (28800 bph) movement, that hacks and can be wound by hand. The dial is protected by very nice domed sapphire glass with an AR (anti-reflection) coating. The most obvious perk of the watch is the material: it's entirely made from CuSn8 bronze. Bronze has the great attribute that it builds up a layer of patina. This is an ongoing process which makes every watch unique. Discolouration is normal with this material. One major benefit is that you can largely bring back your watch in the original condition by using a Cape Cod cloth.
The bronze bezel can be rotated (unidirectional) and of course the buckle on the strap is also made from CuSn8 bronze. The strap is made from genuine shark leather, which is rugged but comfortable. That goes for the entire watch: despite being big it's by no means clumsy, cumbersome or huge and it sits very nicely on the wrist.

This watch comes with 2 year warranty and the beautiful HEROIC18 box with an extra canvas strap and a great leather strap. Worldwide shipping is included.
