Gerald Charles announced the Maestro GC Sport Tennis White on March 31, 2026. It pairs a textured white dial and Velcro strap with a hardened Darkblast Grade 5 titanium case, the brand’s ErgonTeq ergonomic design and an automatic movement. The maker lists a 50-hour power reserve, 100 m water resistance and a 250-piece edition.
What is the Maestro GC Sport Tennis White?
The White is a tennis-themed addition to Gerald Charles’s GC Sport line. The brand says its all-white look pays homage to tennis’s traditional white dress code. Its reference is GC2.0-TX-TNDB-04GR-RSVC_DLE on the product page; the launch announcement gives the final reference characters with hyphens instead of an underscore: GC2.0-TX-TNDB-04GR-RSVC-DLE. Gerald Charles’s launch announcement introduced the watch on March 31, 2026.
Design and tennis-specific details
White dial, strap and titanium case
The watch has a white textured dial and a matching white Velcro strap. Gerald Charles says the strap was developed in-house in Geneva and includes an easy-release system. The case is made from Grade 5 titanium and finished with the brand’s Darkblast treatment.
The brand describes Darkblast hardening as increasing scratch resistance “by up to 10 times.” That is a manufacturer claim, not an independently verified test result. The watch’s caseback is see-through, and the product page lists a date display at six o’clock.

- Read Before You Buy — No Video Output: These adapters support charging and USB 2.0 data transfer, but cannot transmit video signals. Except for standard USB webcams (which use USB data only), they are not compatible with HDMI/DisplayPort cables, video-capable USB-C hubs, or docking stations with video output.
- Convert USB-A Ports to USB-C: Designed to connect USB-C earphones, cables, flash drives, card readers, and other USB-C accessories to standard USB-A ports. Plug-and-play with no drivers or software required.
- Aluminum Alloy Housing: Built with a sturdy aluminum alloy shell that aids in heat dissipation and protects against daily wear and scratches. Designed to maintain a stable and secure connection.
- Compact & Travel-Friendly: The ultra-compact design allows the adapter to stay plugged into your device without blocking adjacent ports or adding bulk, reducing wear and tear on your original USB ports.
- 12-Month Warranty: Backed by a 12-month manufacturer warranty for peace of mind. Designed to meet strict quality control standards for reliable everyday performance.
ErgonTeq and the left-side crown
ErgonTeq is Gerald Charles’s ergonomic design standard. The brand says its approach shapes the lugs, case curvature and strap architecture to increase wrist contact, stability and weight distribution. The crown is on the left side and screws down. Gerald Charles has described this placement on its tennis models as a way to reduce rubbing during play; that stated intention is not proof of on-court performance.

Edition size and reported discrepancy
Gerald Charles’s March 2026 announcement and product listing both say the White edition is limited to 250 pieces. T3’s launch-day coverage reported 200, so published coverage is inconsistent. The manufacturer’s own announcement and product listing are the stronger sources for the maker’s stated edition size.
Price and availability vary by market
The official Korean storefront displayed ₩38,139,000 including VAT. A US official product-page search result displayed $23,800 before sales tax.
