The H. Moser & Cie. Pioneer Tourbillon Limited Edition reference 3804-1205 is a landmark piece in the modern independent watchmaking landscape — a flying tourbillon in stainless steel, from a Schaffhausen manufacture that produces every key component in-house, at a price point that challenges the established hierarchy of haute horlogerie. The Pioneer collection's sports-influenced aesthetic — bold, confident, unafraid of legibility — finds its most technically elevated expression in the Tourbillon.

The blue dial, a Moser signature in its depth and finish, frames the in-house HMC 804 calibre's tourbillon cage at 6 o'clock with understated drama. Luminous hands sweep across the surface, ensuring readability in all conditions. The 42.8mm stainless steel case is a comfortable and confident presence on the wrist at 11.5mm thin, with 10 ATM water resistance — a rarity for a watch of this complication. A three-day (72-hour) power reserve supports comfortable weekend wearing without winding. Two straps are included: a blue textile band and a white rubber strap, both reflecting the Pioneer's sporting-yet-refined character. Produced in 2021 and presented in excellent pre-owned condition with original box and papers.
