This movement is similar to ETA-2428 in terms of components and accuracy. Some experts actually prefer STP 5-15 because of its very nice finishing, beautiful movement marking and jewelled barrel bridge.
The movement is carefully tested in 5 different positions by our watchmaker in Switzerland. The accuracy rate is significantly high, ranging from 0s to +15s a day. We believe that this is the movement you can trust and the watch with this movement can become your reliable timekeeper.
The movement utilizes the well-known Incabloc shock absorber which was invented in Switzerland in 1943. It refers to a spring-loaded mounting system that supports the pivots and jewel bearings from physical shocks or impacts. This contributes to the considerable level of impact resistance for the watch with STP5-15 movement.
Decoration and Finishing
We at Von Doren must admit that we are totally convinced by the look of STP5-15. More interestingly, you can observe the beautiful components through the breathtaking window into its open heart, both from the front and back case. It is a combination between delicate perlage, gilt balance wheel and Nivaflex NM barrel spring. The entire movement is carefully assembled and finally checked by experienced Swiss watch experts.
Feel and Refinement
When it comes to the touch, STP5-15 gives the refined feeling thanks to the firmly clicking crown, even in different positions. This makes you feel effortless during the manual winding. In addition, the STP5-15 beats at 28,800 vibrations per hour, which means a smooth sweeping second hand on the dial.
