Just when you think that you have seen it all a watch comes along and proves you dead wrong. We have seen mystery clocks, transparent dials, and skeletonized movements, but we have never seen a watch with a transparent hour track until this Helbros Invincible crossed our desk. And although this watch is labeled “Invincible”, which was Helbros most prolific line of watches, this model proves exceeding rare.
