EVOLUTION Q-REPEATER BLUE NOTE LIMITED EDITION OF 25

The Quarter Repeater Blue Note CH-1663T-BLSI is a refined yet powerful expression of mechanical sound, where acoustic tradition meets contemporary clarity. Crafted in a 42mm Grade 5 titanium case, this exceptional timepiece transforms the quarter repeater complication into a visual and audible experience, defined by precision, rhythm, and restraint. The Blue Note interpretation tempers bold mechanics with a cool, tonal palette, allowing the complexity of the movement to speak with confidence rather than excess.

At its core beats the historic Calibre C.126, a legacy Chronoswiss movement first introduced in the 1990s and meticulously restored and reimagined in the Lucerne atelier. Hand finished with guilloché plates and modern detailing, the movement is fully integrated into a skeletonised, multi-level architecture. A pusher at 10 o’clock activates the quarter repeater, chiming the hours and quarter hours on demand via two visible hammers positioned at 1 o’clock. The sound is clear, resonant, and deliberate, enhanced by the natural acoustic properties of titanium.

The dial side reveals the choreography of the repeater in motion, combining exposed bridges, refined finishes, and a balanced layout that includes a small seconds display at 6 o’clock. An all-or-nothing safety mechanism ensures flawless activation of the chiming function with every press, preserving both performance and reliability. Advanced surface treatments and subtle colour accents add depth while maintaining a composed, architectural aesthetic.

The Quarter Repeater Blue Note is a watch for collectors who value emotion expressed through precision. It does not shout for attention, yet it commands it through sound, craftsmanship, and mechanical integrity. A modern acoustic instrument shaped by Chronoswiss, where time is not only seen, but heard.
