Without doubt, the most elaborate timepiece in this series is the Troja Opus Temporis, with its unique movement - A charming look combined with functional perfection.

A great pairing – the safety-loving Troja with the magnificent Opus Temporis. This combination brings together ostensibly incompatible aspects into one versatile timepiece which leaves nothing to be desired.
