Inspired by the harsh Cornish Coast, the Sennen Automatic in Green & Silver features a striking design created with meaningful intent. It boasts a beautifully rounded steel case with unique Assegai inspired hands. Paying homage to classic timepieces, the mechanical wonders of the exceptionally high-quality Swiss STP 1-11 movement are visually displayed through the transparent caseback. The design is brought together with a two-tiered enamel dial and a scratch-resistant double domed sapphire crystal, creating a stunning finish. Water-resistant to 10ATM - 100M/330ft. 2 Year Warranty Our green and silver watch is beautifully paired with our classic cognac vintage cowhide strap.
