H. Moser & Cie Pioneer Tourbillon 40mm Mens Watch Burgundy
Ref. 3805-0400
The 40mm case in 18k red gold carries a domed sapphire crystal above and a display caseback below, the latter revealing the in-house calibre HMC 805. That movement runs a one-minute flying tourbillon at six o'clock, its bridge skeletonised to keep the complication visible. A double hairspring aids precision, while a bi-directional pawl winding system and skeletonised red gold rotor handle the automatic winding. Power reserve sits at a minimum of three days. The burgundy fumé dial graduates in tone and carries a sunburst pattern, with faceted appliqué indices bearing Super-LumiNova dots and leaf-shaped hands filled with the same material. A khaki green rubber strap closes with a red gold pin buckle.

Learn more about H. Moser & Cie
Heinrich Moser left Schaffhausen in 1827 for St Petersburg, where he built a substantial watch business supplying the Russian market, and founded H. Moser & Cie in 1828. He returned to Schaffhausen wealthy and became a significant industrialist, financing the Rhine dam that provided the water power for the town's industry — including, later, IWC.
The original company was nationalised after the Russian Revolution and eventually disappeared. The name was revived in 2005 by descendants of the founder, and since 2012 it has been owned by the Meylan family through MELB Holding, which also owns the movement specialist Precision Engineering — meaning Moser makes its own hairsprings and escapements, a rarity at any scale.
The modern brand is best known for restraint taken to the point of provocation. The Concept series removes the logo, the indices, and any text at all, leaving a fumé dial — deep colour at the centre fading to near-black at the edge — and two hands. The Swiss Alp Watch, shaped like an Apple Watch and running a hand-wound movement, was a deliberate joke at the smartwatch's expense.
Moser's complications are serious despite the humour: perpetual calendars with a single central hand for the month, and flying tourbillons with double hairsprings. Production is around three thousand pieces annually.

Frequently asked questions, and things you should know about this watch
Can I swim with it?
Yes. At 120m it is rated for swimming and snorkelling, though not for diving.
Water resistance explainedWill the glass scratch?
Unlikely. Sapphire is second only to diamond in hardness and shrugs off everyday marking.
Sapphire, mineral and acrylic comparedDoes it need a battery?
No. It is automatic — the motion of your wrist winds it, and there is no cell to replace.
Quartz, automatic and solar comparedIs it a men's or women's watch?
Listed as men's, though at 40mm it sits in the range that suits anyone.
Cheapest place to buy
