The Glassbox is no doubt a different look to the Heuer ref. 1158 CHN closer to the ref. 2456 the original solid gold
link Carrera with silver dial which was never offered as a panda and the ref. 2448 the gold-plated three-register from the original Carrera series. There are codes of the ref. 1158 of
link course. The dial design of the modern 39mm Glassbox is a direct copy of the ref. 1158 with an additional running seconds dial at
link six o'clock.
