The new Vulcain Chronograph 1970's with its 38mm diameter and 12.40 mm thick "step-case" is identical to the original and set to appeal to vintage chronograph lovers. It is available in 4 dial colors: blue, black, panda-silver and salmon (each a limited edition). At its heart is a hand-wound SW510 M BH movement with a 63-hour power reserve – a feature appreciated by collectors and daily wearers alike.
