Good afternoon everyone One that came back from overhaul, a clone of the Ollech & Wajs Astrochron, Haste Carribean De Luxe and Jenny Sealab diving chrono powered by the valjoux 72 and a screw down crown (one of the first diving chronos water resistant to 200m), the Britscar diving chrono Ref 2003 (a very rare beast) Best regards Georges
Very nice, Georges. The screw-down crown is really unusual on a chronograph like this, and I love the case-back.
