Each color is limited to 10 pieces. The brand lists the retail price as “upon request,” rather than publishing a numeric price.
Three gemstone versions, ten watches each
Gerald Charles lists three references in its 2025 technical sheet. Each has a silver double-layer dial with 13 gemstone-set hour indexes matching the stones on its bezel.
| Gem version | Reference | Bezel and hour indexes | Edition |
|---|---|---|---|
| Blue | ML1.0-SSPS-WG31-18GS-SBCL | Blue sapphires | 10 pieces |
| Red | ML1.0-SSPS-WG32-18GS-SBCL | Red sapphires | 10 pieces |
| Green | ML1.0-SSPS-WG43-18GS-SBCL | Green tsavorites | 10 pieces |
All three bezels have 60 baguette-cut stones. The technical sheet does not specify different prices by color. Check with Gerald Charles or a retailer for current availability; a product page’s stock status is not a reliable comparison across all three references.
Case and integrated-bracelet design
The Masterlink adapts the square-based form of Gerald Charles’s Maestro case, including the characteristic curve at six o’clock that the brand calls its “smile.” The case measures 38 × 38 mm and is 7.99 mm thick. It is made from 316L stainless steel, with a white-gold bezel shaped to follow the case’s irregular architecture.
