Originally introduced in 2014, the Venturer Tourbillon Dual Time features a unique dual time function as well as an interchangeable tourbillon module, presented in a 41.5 mm x 14.3 mm case crafted from either 18K white or red gold.
There are five variations in total (red gold/gold dial, red gold/silver dial, white gold/gray dial, white gold/blue dial, white gold/white dial). The version pictured comes in white gold with a white lacquered dial, black transferred Roman numeral indexes, blued leaf-shaped hour and minute hands, and a red leaf-shaped second-time zone hand (which can be concealed by setting it to the same time as the home time hand).
Uniquely, at the bottom of the dial is a one-minute tourbillon that is visible through a circular aperture, and that features an open-worked bridge, offering an impressive view of the free-sprung balance wheel, tourbillon cage, escapement, and other regulation components below. Additionally, in regards to servicing the tourbillon, this module is completely interchangeable, which makes assembly, adjustments, and servicing easier than a traditional tourbillon.
Highlighting the tourbillon is a metal fan-shaped section of the dial that is set on top of the dial between 4 and 8 o’clock, and that is decorated with curved stripes.
Underneath the dial is automatic caliber HMC 802 which is made in-house, measures 34 mm x 6.5 mm, beats at 3Hz (21,600 vph) and has a 3-day power reserve.
According to Moser, “A further improvement was possible with the addition of a Straumann Double Hairspring® within the tourbillon. With the gravitational influence typical in a hairspring compensated by these meticulously paired hairsprings, the result is a tourbillon with enhanced accuracy and greater precision.”
Naturally, the movement is finished to a very high level, with Geneva stripes, chamfered and polished edges, polished screws, and a beautiful red gold skeletonized rotor – all visible through the sapphire caseback.
While the market for gold tourbillon watches is more saturated than it has ever been, Moser stands out with the interchangeable tourbillon module, and useful dual-time functionality, which is particularly unique in a dress watch.
