The 45mm case of this Graham Prodive commands attention with its assertive design and solid diving credentials. Its signature left-mounted trigger lever for the chronograph start and stop ensures easy handling even with gloves on, while the unidirectional bezel allows precise decompression timing. Water-resistant up to 600 metres and equipped with a helium escape valve, this watch is built for extreme underwater performance as much as it is for an audacious wrist presence.

Inside, the automatic calibre G1750 (also known as G1734 in earlier iterations) runs at 28,800 vibrations per hour, offering a 48-hour power reserve and supporting both chronograph and small seconds functions. The black dial with bold and contrasting index markers ensures excellent legibility, and the robust strap complements its adventure-ready character. The Chronofighter Oversize Prodive 2CDAV.B04A.K80S captures the spirit of fearless exploration in true Graham fashion.

At Second Movement, the pre-owned division of Ethos Watches, we adhere to a rigorous verification process where expert watchmakers carefully inspect every watch to certify its authenticity, ensuring it is not counterfeit. We also go to the maximum extent possible to ensure that the timepiece is not a stolen property and that all duties are paid. However, in the absence of any central database, a 100% verification is unlikely for any pre-owned entity in India. Nevertheless, we can still provide a provenance guarantee for watches purchased from Ethos.
