Davosa Watch Ternos Medium Automatic 16619505. The Ternos Medium has the very same quality characteristics of the Ternos Ceramic, it only differs in its dimensions. The case has a diameter of 36.5mm and a height of 11.8mm and is thus more suited to a narrower wrist. 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 longlasting, 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.
