First debuted at
Baselworld 2013, the
Type 3 was the brand's first oil-filled, mechanical watch and a follow-up to the
Zero series, which introduced us to
Ressence’s method for displaying time. The goal was to achieve a “water drop effect” - optimising legibility from any angle, creating an optical effect of the indications appearing on the glass itself. This achievement was not without its challenges. Until the release of the
Type 3, oil-filled watches had only been achieved using quartz movements, as the escapement of a mechanical timepiece struggled to oscillate properly in a viscous fluid.
To keep the mechanical movement separate from the oil, the watch is split into two modules; a lower-half comprised of a customised
ETA 2824/2 ébauche, and a hermetically-sealed, display module, or
ROCS (
Ressence Orbital Convex System), flooded with 35.7 ml of oil. Composed of 215 parts, 44 gears and 47 jewels, the gears in the
ROCS calculates the hours, day and date, taking only the minute as a reference from the movement. Unlike the
Type 1, there's no mechanical link between the movement and the
ROCS, instead using a magnetic coupling to tie the modules together.
The ’B’ in ‘
Type 3B’ refers to the black finish of the dial and winding rotor, giving the watch an industrial feel and matching the colour of the case. The orbital display shows hours and minutes, as well as the day of the week (with weekends shown in orange) and the date on the outer edge of the dial. All indicators are filled with generous quantities of
Superluminova, for maximum low-light visibility.
With temperature change, expansion and contractions of the oil might ordinarily cause bubbles of air (due to oil contraction), or leakage (if the oil expands), and so bellows are integrated in the upper module, which compensates for the changes in oil volume and make the watch wearable in temperatures from -5 to +50 degrees.
With two highly-domed, sapphire crystals covering both sides of the watch, the Type 3 has an almost pebble-like appearance and is clearly influenced by current industrial design trends. The black DLC-coated, grade 5 titanium case measures 44 mm, yet wears smaller than expected, due to the absence of the external case seen in traditional watchmaking. The watch also goes without a traditional crown, increasing the organic feel, with the user instead interacting with the domed, sapphire case-back to wind the movement and set the time.
This
Type 3B comes as a full set, with its original box, product literature and two brand new,
Ressence straps. It also has its original stamped warranty card, detailing its original purchase from
Martin Pulli, Philadelphia, in 2014.
Viewings can be arranged in Central London by appointment only.
