BALTANY B4030 Bronze Automatic Watch – Seiko NH38, Sapphire Crystal, 200m Water Resistant

Patina Tells Your Story.

The BALTANY B4030 is a vintage-inspired field watch with genuine character — a solid bronze case that develops a unique patina over time, paired with Swiss Super-LumiNova hands and a Seiko NH38 automatic movement. No two will ever look exactly the same.
