Girard-Perregaux Sea Hawk

Girard-Perregaux Sea Hawk is a line of Swiss diver's watches from the Girard-Perregaux manufacture, which fits its models with in-house calibres. The collection's key feature is its asymmetric case: the crown is moved to 4 o'clock and tucked between protective shoulders, so it does not press into the wrist and is less exposed to knocks. The models have a screw-down crown, sapphire crystal and a rotating bezel with a scale for timing dives.

The collection includes the steel Sea Hawk II and the platinum Sea Hawk II Pro Tourbillon BMW Oracle Racing edition. The steel watches use an in-house automatic calibre and show the date and power reserve. The Diver's Watch 42 mm has a black dial with large Arabic numerals, the model dedicated to John Harrison a white one. The platinum version is a watch of another level: a hand-wound tourbillon with a woven-texture carbon-fibre dial. The choice within the collection comes down to three questions: case material (steel or platinum), movement (automatic or tourbillon) and case size.

Each product page lists the reference, calibre, movement, power reserve, case size and material, water resistance, bracelet or strap, condition and what is included.
