Davosa Watch Ternos Diver Lady White 16619510. The Ternos Ceramic series is one of DAVOSAs most popular models. The series name derives from the Latin term for everlasting and the choice of name is no coincidence. Its components include a high tech, ceramic bezel, scratch resistant, transparent, anti reflective sapphire crystal, a meticulously crafted stainless steel case capable of withstanding pressures of 20 ATM, a precise Swiss DAV 3021 automatic movement, ensuring long lasting, functional reliability. The design is very subtle for a sporty divers watch and truly deserves the classic timeless attribute, the Ternos not only cuts a fine figure over a wetsuit, but looks stylish in combination with a single breasted business suit.
