Brand vibe
A young French house with one product and a lot of conviction. INERCY's entire catalog is the Collection ONE: a 42mm steel time-only with a Seagull-based flying tourbillon caliber displayed through a tinted plexiglass dial. The branding leans hard into "réorienter la perception du temps" — a philosophical pitch wrapped around an accessibly priced complication. The Skeleton V2 anniversary edition (100 numbered pieces) is the closest thing to a halo; the colored ONEs (Blue, Green, Red, Dark/Light Grey) are the everyday entry points.

⚠ Current Section 122 rate expires Jul 24, 2026 — rates may change.
EU framework deal paused after SCOTUS ruling. Currently flat 10% Section 122. [Note as of June 17, 2026: USTR has proposed new Section 301 forced-labor tariffs (~10–12.5%) that, if enacted, would stack on top of current rates. Still in public-comment phase.]
Tariffs are assessed based on where the watch is assembled, not where individual components originate. A watch with a Japanese movement assembled in the US incurs no import duty.
