It features a Rare Handcrafts dial with hand-guilloched swirling pattern visible beneath a Grand Feu blue green enamel (flinqué enamel technique). The dial is also set with 12 baguette-cut diamond hour markers (0.45 ct) and features a transfer-printed “only one” inscription. 

The sapphire crystal case back bears the metallized inscription “Only Watch 2024”. This unique timepiece is fitted on a patinated blue green alligator leather strap with fold-over clasp.
