Gerald Charles

Maestro GC Sport


LIMITED EDITION OF 200 PIECES The GC Sport fading russet-coloured dial, with applied Arabic numerals at 3, 9 and 12, captures the spirit of the clay court tennis season. The watch's ergonomic case measuring only 8.7mm in thinness and its lightweight design in polished Grade 5 titanium, make it possible for tennis players to wear it during the game. The matching vulcanized rubber strap is decorated with the Maison's signature Clous de Paris motif on the top side, and with Gerald Charles logo tapisserie on the other.

Stronger and shock resistant Ref. GCA 3002

For the GC Sport, the Gerald Charles GCA 3002 automatic manufacture movement has also been specially adapted. It has been made stronger and up to 40 per cent more resistant to shocks and stresses caused by high-impact movements. The rotor has been evolved, too. It is now more resistant, so that it doesn’t wind the movement too quickly during intense physical exercise, or risk overwinding it.
