Hermès' Arceau Duc Attelé serves up an impressive level of physical and aural depth, from the dial right through to the sapphire bridge for the strikework on the rear of the timepiece. The sapphire bridge itself serving both to enhance the sound of the minute repeater while also providing an unhindered view of the repeating works in action.

The choice to fashion the hammers for the gongs in an equestrian theme is a fitting, subtle, and particularly delightful touch. While Patek Philippe's Advanced Research division gave a nod to the tuning fork with the amplifier they devised for the Fortissimo, the Arceau Duc Attelé also marks the first time I can recall the use of tuning forks to serve as gongs.
