Fears has spent much of 2026 broadening its everyday-watch language, but the Arnos Opera Black pulls the brand firmly back into evening-wear territory.
It’s a rectangular dress watch built around a sharply literal idea of black tie, using polished onyx, white lacquer and elongated Roman numerals to turn formal dress codes into dial architecture.
At a glance
- The Fears Arnos Opera Black joins the Arnos collection as a non-limited rectangular dress watch.
- Its polished onyx dial features a white lacquer centre and elongated Roman numerals for a tuxedo-like black-and-white display.
- It is priced at £4,350 including VAT and is powered by a customised automatic Sellita SW1000 movement.
A dial built around evening dress
The Opera Black is less about embellishment than theatrical restraint.

Its dial is made from a single piece of polished onyx, interrupted by a white lacquer disc at the centre and framed by long Roman numerals around the edge.
The black-and-white arrangement gives the watch its formal character, echoing the contrast of a dinner jacket and shirt without turning the idea into costume.
The white Roman numeral at 12 o’clock strengthens that impression, reading almost like a glimpse of shirt between jacket lapels.

The 5 and 7 markers add another neat visual cue, recalling the suggestion of shirt cuffs at the edge of a sleeve.
The Arnos case keeps the drama contained
Rectangular watches can feel larger than their measurements imply, and the Arnos Opera Black leans into that presence.
The case measures 33.5mm in length and 22.6mm in width, with the lugs extending the on-wrist length to around 40mm.

At approximately 8.4mm thick, it remains slim enough for the dress-watch brief.
The polished case has clean lines and a slight curve, helping it follow the wrist rather than sitting flat and stiff.
That curve also sets up the strap choice, with the watch supplied on both an Obsidian Black Epsom leather strap and a Grosgrain silk strap with a ribbed texture.

A simple automatic movement beneath a solid back
Fears keeps the reverse side understated with a solid brushed caseback rather than an open display.
Inside is a Sellita SW1000 automatic movement customised to show only hours and minutes.
The movement offers a 46-hour power reserve, while time-setting is handled through a knurled crown at 3 o’clock.
That pared-back configuration suits the watch’s purpose, keeping attention on proportion, surface and the formal dial composition.
