The Watch
The 40 mm case of this timepiece is crafted in stainless steel. The crystal over the case is scratch-resistant sapphire, while the case back is transparent. The crown, engraved with the "H" logo, is positioned at 3 o'clock. The transparent case back is the origin of the name "Viewmatic", as it allows a detailed view of the automatic movement housed within.
The Dial
Round in shape and featuring an immaculate white finish, the dial of this iconic Viewmatic model showcases a beautiful double-circle finish - with an elegant "clou de Paris" guilloché pattern in the inner circle. The hour and minute hands are silver-toned with luminescent treatment. Baton indices are paired with Arabic numerals at 6 o'clock, 9 o'clock, and 12 o'clock to mark the hours, while a black minute track runs around the edge of the dial. The date window sits at 3 o'clock, with the watchmaker's name at 12 o'clock and the model name at 6 o'clock.
The Movement
This Viewmatic model is powered by a Swiss-made automatic movement. The H-10 caliber, based on an ETA C07.611, features 25 jewels and beats at 21,600 vibrations per hour. It delivers hours, minutes, seconds, and date via a quickset window, with automatic winding via a ball-bearing rotor. The power reserve for this movement type is 80 hours.
The Strap
This timepiece comes with a crocodile-finish leather strap. In brown with matching stitching, it fastens with a silver-tone pin buckle. The lug width is 20 mm and the reference is H600.325.100.
Water Resistance
This timepiece is not designed for scuba diving or swimming. Its water resistance is rated at 5 ATM, meaning it can be submerged briefly, but not for extended periods.
