Gerald Charles Gives the Maestro GC Sport Tennis a Turquoise Turn

Gerald Charles has built much of its modern identity around one unmistakable shape, and the Maestro case still has room to move.

The new Maestro GC Sport Tennis Turquoise Edition takes the brand’s performance-minded sports watch into brighter territory, pairing a light turquoise dial and Velcro strap with a compact Darkblast titanium case.

It’s a watch that leans into the odd charm of Gérald Genta’s final personal brand without losing sight of the practical brief behind the GC Sport line.

At a glance

A Genta silhouette made for the court

The Maestro case remains the centre of the Gerald Charles universe, and for good reason.

Its asymmetric profile, originally inspired by Roman Baroque architecture, is instantly recognisable without behaving like a conventional sports-watch case.

That makes the GC Sport Tennis an unusual proposition.

It has the technical brief of a modern high-activity watch, yet it keeps the eccentric architectural language that links it directly to Gérald Genta’s design legacy.

The case measures 39mm across and 41mm in length, with a thickness of just 9mm.

Those dimensions matter because this is not simply a lifestyle sports watch dressed in athletic colours.

The Maestro GC Sport family was developed with input from ATP Tour tennis players, with the aim of creating a watch that could stay on the wrist during physically demanding play.

For this turquoise edition, the case is made from matte Darkblast grade 5 titanium, chosen for low weight and durability.

The screw-down crown sits on the left side of the case and uses a Clous de Paris grip, a small but distinctive detail on an otherwise streamlined silhouette.

Turquoise without losing the watchmaking detail

The headline change is the dial, which swaps the previous tennis-ready yellow fumé treatment for a grained turquoise surface with a gradient effect.

It’s bright, but not flat.

The grain and tonal shift give the dial more depth than a simple colour refresh, while the white railway-style minutes track keeps the layout crisp.

Applied Arabic numerals appear at 12, 3 and 9 o’clock, with baton markers filling the remaining positions.

A framed date aperture sits at 6 o’clock, bringing symmetry to a watch case that deliberately avoids it.

The baton hour and minute hands, indices and dial markings use white Super-LumiNova with green emission in the dark.

The effect should suit the watch’s tennis connection, where legibility and low wrist weight matter more than decorative excess.

The textured turquoise Velcro strap completes the tone-on-tone look and is fitted with an integrated Darkblast titanium buckle.

A slim Vaucher calibre reworked for impact

Inside is the automatic calibre GCA2001, produced by Vaucher Manufacture Fleurier.

The movement is notable not only because of the maker behind it, but because it keeps a very slim 3.7mm profile while being adapted for a more punishing use case.

For the GC Sport Series, Gerald Charles states that the movement has received a 40 percent increase in shock resistance.

The rotor has also been re-engineered to help prevent overwinding during intense physical activity, a relevant consideration for a watch designed to handle tennis rather than merely reference it.

The calibre runs at 28,800 vibrations per hour and offers a 50-hour power reserve.

It also includes hacking seconds, a practical feature for precise time-setting.

Visible through the sapphire caseback, the golden customised rotor carries the brand’s honeycomb motif.

Details & Specifications

The Maestro GC Sport Tennis Turquoise Edition is a sharp example of where Gerald Charles is strongest right now.

It doesn’t try to make Genta’s case more conventional, and it doesn’t treat the tennis brief as a colour exercise alone.

For collectors who want a lightweight independent sports watch with a recognisable silhouette and a serious movement pedigree, this may be the most playful GC Sport yet.
