Hamburg: Clear Design for Every Day
A measured take on everyday watchmaking, Hamburg pairs purposeful proportions with an uncluttered display. Its 42.0mm case creates a balanced frame for the dial.
The watch combines sapphire-crystal protection with water resistance up to 5 ATM, bringing practical resilience to its refined, understated character.
The Ronda 715 keeps time dependably, while the strap provides a composed finishing touch. The result is easy to read, easy to wear and rewarding at a glance.

A few things you might still wonder
How does an automatic watch work?
How does an automatic watch work?
A rotor turns as your wrist moves, winding a spring that stores energy. That stored energy powers the movement, so there is no battery to replace.
What if I haven’t worn it for a few days?
What if I haven’t worn it for a few days?
When the power reserve runs down, the watch stops. Follow its winding instructions, reset the time, and wear it again.
How should I care for the leather strap?
How should I care for the leather strap?
Keep leather away from prolonged moisture and direct heat. Wipe it gently with a soft cloth and let it dry naturally if damp.
Time well worn
The Calibre Behind Hamburg dark blue
The Ronda 715 gives Hamburg its measured pulse. Its stated accuracy is -10/+20 seconds per month. Useful functions include date and hacking seconds. Chosen for clarity and reliable daily use, the mechanism supports the watch without distracting from its design.
A Better Fit in Vintage mocha
The strap completes the design of Hamburg. Made from leather, it follows the wrist with a balanced feel and keeps the composition coherent from case to clasp. The material will soften with wear and gain a more personal character over time.
