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 microbrand 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 microbrand watch enthusiasts who gather annually at Micro Praha.

Once fully charged, the watch can operate for up to five months without further exposure to light, combining everyday practicality with sustainable timekeeping.
