in Bronze / Black


The M-53 Bronze is part of Lum-Tec's limited-edition bronze series of men s wristwatches.

The M-53 has a solid CuSn8 bronze case that will develop a patina over time. Each case is unique and will tarnish differently, and the corrosion actually protects the metal underneath. Choose whether to polish it back to new or allow it take on its own unique character.

Winding a mechanical watch

The M-53 is an automatic mechanical watch.

Mechanical watches fall into two camps: either they’re automatic and wind themselves with a mainspring powered by your natural arm motion, or they’re manual and require you wind the mainspring periodically by turning the crown (the small knob on the watch case) to provide the energy sufficient to run the watch. If the spring in a mechanical watch is not wound, the watch stops.

When you receive your watch, you may need to either wind the mainspring (manual) or wear it on your wrist a while (automatic) for the hands to start their movement.

Water Resistance

300 meters/990 ft (Water resistant)

Officially rated for scuba diving. Now get out there and get your certification

Remember that though your watch might be rated to 100 meters or deeper, try to keep it out of the shower or the hot tub. Prolonged exposure to steam can damage the gaskets and weaken the seals that otherwise keep everything watertight.


Wipe clean with a dry microfiber cloth (the kind that come with sunglasses are usually perfect). If you have a watch rated to 100m or deeper, rinse thoroughly with cold tap water after immersion in the ocean.
