Ferro AGL 2 Automatic

The watch is noted for its 42mm brushed stainless steel case, 11mm thickness, double-domed sapphire crystal, and a grippy onion crown with a smooth locking mechanism. It offers 100m water resistance and comes with an Italian leather strap, all powered by a Swiss Ronda 5040B quartz chronograph movement.
