What is an Automatic Watch?
What is an Automatic Watch?
An automatic watch is powered by movement, not a battery. As you wear it, your wrist naturally winds the movement to keep it running.
If left unworn for around 40 hours, it may stop - simply wear it again or gently wind the crown to restart it.
Built for Precision & Presence
Featuring a polished black ceramic bezel, luminous Mercedes-style hands, and a scratch-resistant sapphire crystal, this timepiece blends classic Submariner styling with rugged performance. It’s more than a watch, it’s your daily companion.
