WatchTime Düsseldorf 2025: “U50 B” – submersible precision from SINN
The SINN "U50 B" model is a precision instrument for divers and, at the same time, a strong statement in terms of design. The striking, matte blue dial immediately draws the eye, signaling professionalism and underscoring the uncompromising functionality of this watch.
This is not least due to the white, luminescent indices and hands, which create a perfect contrast. The result: a harmonious overall appearance with comfortable legibility. In the best SINN tradition, the "U50 B" combines sophisticated design with technical expertise.

"The rush has always been very large in recent years, and we often observed that some interested parties couldn't even get through to us. This year, we will therefore exhibit on a larger stand, hopefully making it more pleasant for visitors to experience the watches in person."
Lothar Schmidt (SINN owner)

Lothar Schmidt (SINN owner):
"Guests can try on almost all models from our extensive collection and interact personally with SINN employees. WatchTime is also a wonderful opportunity for us to present new diving watches. And a true SINN classic, which we have given a new look together with a partner, is sure to attract attention.
All in all, WatchTime Düsseldorf is a wonderful opportunity to exchange ideas with mechanical watch enthusiasts and immerse yourself in this beautiful world together."
The 41-millimeter case and crown are made of high-strength, seawater-resistant submarine steel of the highest non-magnetic grade. A material normally used only in extreme maritime conditions. Its underwater suitability up to a pressure of 50 bar has been tested and certified by an independent institute.

The captive diver's bezel is particularly scratch-resistant, as it has been additionally hardened with TEGIMENT technology. A practical detail: the crown is located at the 4 o'clock position, preventing it from being pressed into the back of the hand.
The Sellita SW 300-1 automatic movement is responsible for the precision of the hours, minutes, seconds and date displays.
