ACF-03

Every aspect of engineering and design ergonomics has been optimised for comfort and performance.

Close-up front view of a cushion-shaped titanium watch shot straight on against a white background, with the black suede strap extending to both edges of the frame. The wide, domed case emphasises the deep curvature of the bezel and the subtle concavity of the matte grey dial. The open-loop blue hands and slim orange seconds hand cast soft shadows across the dial surface.Side view of a sleek wristwatch with a minimalist face, orange hour hand, and blue minute hand on a black strap.

Soulful

The quiet ritual of a manual-wind calibre.

Rear view of a skeleton mechanical watch with a cushion-shaped titanium case, exposing the movement through a transparent caseback. Ruby jewels, a large gear train, and machined bridges are visible. The watch sits on a black suede strap with a polished folding clasp, photographed against a white background.Rear view of a skeleton mechanical watch with a cushion-shaped titanium case, exposing the movement through a transparent caseback.

Calibre AMB-02/1

Engineered by OISA. Its mechanical character blends the soul of traditional horology with the precision and reliability of modern engineering.

Exploded diagram of a mechanical watch movement showing three layers separated vertically. The top layer is a dark titanium bridge plate with cutouts and recesses. The middle layer displays the gear train assembly with four components labeled A through D in orange: A indicates the barrel and mainspring assembly, B the large gold escape wheel, C the gear train stack with ruby jewel bearings, and D the balance wheel. The bottom layer is the main movement plate in light grey with machined cavities for housing each component.

Features

A
3.5 Hz

The calibre beats at 3.5 Hz, offering a balance between precision, stability and daily reliability.

B
60 Hours Power reserve

The manually wound movement delivers a 60-hour power reserve, allowing the watch to run comfortably beyond two full days.

C
Optimised torque consistency

Its architecture is designed to deliver more consistent torque throughout the power reserve, supporting stable performance over time

D
Improved accuracy

With its free-sprung balance and refined regulation, the calibre achieves improved chronometric accuracy of ±3 seconds per day.

Baseplate and bridges

Crafted in Grade 5 titanium. Finished entirely by hand.

Close-up of a two-piece mechanical watch bridge plate in dark titanium, shown at a slight angle against a white background. The upper section features an open-worked, architectural design with large circular apertures, a three-pronged central spider bridge, and precision-machined channels connecting the bearing seats. The lower section is a separate bar bridge with a large circular cutout and symmetrical screw bosses on either side. The sandblasted matte finish and angular cutouts give the component a structural, industrial aesthetic.Close-up of a two-piece mechanical watch bridge plate in dark titanium, shown at a slight angle against a white background.

Split gear train

Its split gear train and free-sprung balance improve stability, reduce functional interference, and preserve accuracy through finer adjustment and greater shock resistance.

Isolated close-up of a mechanical watch gear train assembly against a white background. The stacked components show a large brushed steel barrel with a circular-grained ratchet wheel at top, meshing into a cascading series of gold and steel pinions and wheels with red ruby jewel bearings. At bottom left, a gold balance wheel with a brass roller jewel and pallet fork is visible. At right, a brushed steel lever plate with a notched locking detent anchors the escapement. The mix of polished gold, brushed steel, and deep red jewels highlights the layered mechanical complexity of the movement.Isolated close-up of a mechanical watch gear train assembly against a white background.

Case

Tonneau-pebble, crafted in Grade 5 titanium. Bead blasted finishing.

Isolated view of a hollow watch case middle in dark sandblasted titanium, shown at a three-quarter angle against a white background. The cushion-shaped case has no dial or movement installed, revealing its open interior. A knurled crown is fitted to the right side. The case shows integrated lug geometry with smooth, rounded transitions from the bezel edge down through the lugs, with a small pusher port visible on the left side. The matte finish and monolithic form emphasise the case's sculptural quality as a standalone component.Isolated view of a hollow watch case middle in dark sandblasted titanium, shown at a three-quarter angle against a white background.

Titanium dial

Engraved quarters and indices (colour customisation available upon request)

Cutaway render of a cushion-shaped watch showing the relationship between the transparent outer case and the inner titanium dial. The see-through case reveals the sealed air gap between the crystal and dial surface, illustrating the watch's water resistance construction. The matte grey dial features open-loop blue hour and minute hands with an orange seconds hand, set against a minimalist minute track with numerals at 12, 3, 6, and 9.

Front three-quarter view of a cushion-shaped titanium wristwatch against a white background. The heavily domed, pebble-like case has a sandblasted matte finish with no visible lugs, flowing directly into a wide black suede strap with a light grey interior and a polished titanium folding clasp. The clean grey dial features a minimalist minute track with numerals at 12, 3, 6, and 9, open-loop blue hour and minute hands, and a slim orange seconds hand with a blue centre pip. A small knurled crown sits flush at 3 o'clock.

Front three-quarter view of the same cushion-shaped watch in an all-black colourway against a white background. The case, dial, crown, and folding clasp are finished in deep matte black, creating a near-tonal composition. The dark grey dial retains the open-loop hand design in a matching dark finish, with the slim orange seconds hand providing the only colour contrast. The wide black suede strap shows the same lug-free integrated form. The overall effect is more stealth and graphic than the titanium version.
