"BETA" Prague Edition
Sunrex “BETA” Prague Edition
Limited to only 30 pieces.
Collaborated with Infinity Watches.
Celebrates the expanding microbrand community in Prague.
Created in collaboration with Infinity Watches, organizer of Micro Praha Festival, the SUNREX "Beta" Prague Edition is a special collector's edition based on the acclaimed "Beta" chronograph.
Limited to only 30 individually numbered pieces worldwide, this exclusive release celebrates the growing independent watch community in Prague. The highlight of the Prague Edition is its distinctive running seconds display, featuring the red, white, and blue colours of the Czech national flag, a tribute to both the city and the passionate enthusiasts who gather annually at Micro Praha.
Like the standard "Beta", the Prague Edition is powered by the proprietary Viluminus™ solar-powered chronograph movement, which converts both natural and artificial light into energy. Once fully charged, the watch can operate for up to five months without further exposure to light, combining everyday practicality with sustainable timekeeping.
Inspired by 1950s pilot chronographs, the "Beta" Prague Edition maintains the model's signature black dial, gilt accents, DLC-coated rotating bezel, and vintage instrument aesthetic, while introducing an exclusive colour detail available only to this limited collaboration.
Each watch is individually engraved with one of thirty dedicated serial numbers, making every piece a unique collectible for Micro Praha participants and independent watch enthusiasts alike.

OLD TECH, MODERN TAKE
Viluminus: Solar-Powered

NOD TO THE PAST, MADE FOR THE PRESENT
Pilot’s watches may have started as essential gear for military aviators during World War II, but by the 1950s, they had found a new life both in the cockpit and in everyday life. This was the decade these watches became must-have tools for pilots and symbols of adventure for everyone else.
The "Beta" Prague Edition Pilot’s Chronograph is our nod to that era—a time when aviation was as much about precision as it was about guts and style.
In the 1950s, pilots needed watches they could rely on, especially in low-light conditions. That's why watch designers from this era designed pilot watches with large, easy-to-read dials and luminous numerals and hands. It made sure they were easy to read at a glance. The "Beta" Prague Edition carries this forward.
And let’s not forget the bezel. In the 1950s, rotating bezels weren’t just for show—they were practical tools, helping pilots track time or calculate fuel consumption mid-flight. The "Beta" Prague Edition keeps the tradition alive with a DLC-coated bezel that's durable and functional, whether you're flying or just on the move.
That’s what we’ve captured with "Beta" Prague Edition, a watch that’s as much about looking good as it is about getting the job done.
BECAUSE TIMELESS STYLE AND EVERYDAY PRACTICALITY SHOULD ALWAYS GO HAND IN HAND
