The Andersen Genève x Benjamin Chee HH Celestial Voyager Supersonic is a limited-edition world-time watch built around a Concorde-inspired scene: a delta-wing aircraft above New York, rendered in champlevé enamel. Its reported 37.7 mm case pairs a platinum mid-case with titanium bezel and caseback, while a restored and upgraded A. Schild-based automatic movement drives the world-time display.
What makes the Supersonic edition distinctive?
The Supersonic belongs to the Celestial Voyager series, whose first version appeared in 2021. This edition draws its visual theme from Concorde and its transatlantic flights, but the aviation reference is design context: the watch is presented as a world timer, not as an instrument with specialized flight functions. Monochrome Watches’ December 13, 2023 feature describes the edition and its specifications.
A Concorde scene in enamel
The focal image places a delta-winged aircraft above the Chrysler Building. The source describes the scene as champlevé enamel applied in recesses carved into a white-gold dial plate, with more than ten shades built up and fired in multiple layers. It also describes tiny gold particles, or paillons, used to suggest stars. These are the article’s descriptions of the dial craft, rather than independently verified production details.
Aventurine forms the city ring, and New York is highlighted with rose-gold powder. The layered cityscape, aircraft and starry motif give the watch its nighttime travel narrative; the functional display remains hours, minutes and world time.

How does the world-time display work?
Two crowns divide the adjustments. The crown at 9 o’clock sets the city ring, while the crown at 3 o’clock is used for winding and setting the time. That separation is the key practical detail: the watch’s world-time indication is adjusted through its city ring rather than through an aviation-specific complication.
Case and movement specifications
| Specification | Reported detail |
|---|---|
| Case materials | Platinum mid-case; titanium bezel and caseback |
| Dimensions | 37.7 mm across; 10.1 mm thick |

These figures are reported by Monochrome Watches, a specialist editorial source, rather than an official brand specification sheet. The case dimensions make the watch relatively compact on paper, while the 30 m rating is a modest water-resistance specification; neither number by itself establishes wearing comfort or suitability for water use.

Quick Recap
Best Value
- VK63 MECHA-QUARTZ CHRONOGRAPH: The WD1863 uses a VK63 mecha-quartz movement with a central 1/5-second chronograph hand, 60-minute counter, running small seconds and a 24-hour display. The pushers control start, stop and reset, combining quartz accuracy with crisp mechanical-style chronograph action for practical elapsed-time measurement.
- BUBBLE SAPPHIRE CRYSTAL & ALUMINUM BEZEL: The raised bubble-style sapphire crystal adds depth above the dial, while a high-clear inner AR coating helps reduce reflections. A 316L stainless steel case and bracelet provide a solid everyday build, and the fixed aluminum bezel creates a defined frame around the vintage chronograph display.
- SUPER BGW-9 BLUE LUME: BGW-9 super luminous material is applied to the hands, hour markers and selected dial details. After exposure to light, these elements produce a blue glow that supports quick time reading in darker surroundings. Coverage follows the individual dial design and remains clearly arranged around the three-register chronograph display.
- 100M WATER RESISTANCE: The screw-down crown and screw-down case back support a 100M water-resistance rating for daily wear and suitable surface-water use. Always tighten the crown fully before contact with water, do not operate the chronograph pushers while the watch is wet or submerged, and avoid hot water, steam and diving. Water resistance should be checked periodically as seals age.
- COMPACT 39MM WRIST PROFILE: The WD1863 measures 39mm across the bezel, with a 41mm mid-case, 46mm lug-to-lug length, 12.9mm thickness including the raised crystal and 20mm lug width. These proportions balance the detail of a three-register chronograph with a wearable footprint. The 20mm bracelet remains proportionate to the case, while the raised crystal adds vintage depth to the compact design.
