EPOS 3435 ‘Verso’ – The story behind


The key aspiration of EPOS has always been to produce Swiss mechanical watches exclusively. EPOS has invariably placed the Swiss watchmaking craftsmanship at the core of its philosophy. This approach is underlined with a high-end decoration and finishing of each model’s movement. The ‘Verso’ watch is the logical consequence of an evolutionary development since the first EPOS watches were put on the market. Though, it’s a pity that in the past the beautifully decorated Unitas 6497 movement was only visible through the backside of the watch. That’s why EPOS designers decided to evolve the movement from supporting- to leading role and thus ascended to the center of the design. Its central mechanical functions are now directly visible on the owners’ wrist.

The EPOS 3435 ‘Verso’ is an homage to the EPOS ‘Hundertwasser’ pocket watch, which took the well-known Austrian painter Hundertwasser more than seven years to complete. The unique masterpiece subsequently has been manufactured by EPOS as a limited edition in 1993 and is held in a typical ‘Hundertwasser’ design. The watch sports two pairs of hands on the back- and on the front-side. True to the philosophy of its artist the two pairs of hands run reversed, as to show the paradoxical of time. EPOS engineers and designers derived the idea of showing the time at the movements’ back to the EPOS 3435 ‘Verso’. Allowing the timepiece to be used as an everyday watch, EPOS engineers had to find a way of reversing the movements’ mechanism.


The most challenging issue was to reverse the function on the movements’ back, which wasn’t the case in the ‘Hundertwasser’ watch. Engineers had to rethink the functions of the Unitas movement and everything connected to the ‘Verso’ project was depending on this complicated task. This is the reason why the ‘Verso’ is released more than 20 years after the ‘Hundertwasser’, everybody thought it’s impossible. Last year our chief-engineer suddenly had a brainwave and came up with the solution to use new gearwheels and to place it on top of the main bridge on the timepieces’ right. Luckily it worked right at the first prototype and the ambitious project took shape.

The second step included the design of the watches front. As the position of the gearwheels was defined, the dial had to be positioned on the right as well. The nice side effect of the decentralized position is that the movement can shine in it its full splendor. Finally, the dial had to be mounted on top of the movement. Engineers used a three-pronged securing to stabilize the dial. The problem was that there was only space for two screws. That’s why our engineers decided to mount the movement with two synchronous screws and one safety layer at 2 o’clock position.

In the end the design and function of the backside was a big question mark and it took our team quite some time to figure that out. At first the general opinion was to design a closed back, because the front of the Unitas without a dial isn’t very appealing. But this solution seemed too simple, compared to the timepieces’ beautiful front-side. All of a sudden the EPOS chief-designer, who has a background in Medicine, had an excellent idea. The small-second, which remained at the original front position could be used as a Pulsometer. The idea was finalized with a transparent mineral for the small-second, surrounded by engraved markings.
