Third generation (launched November 2024), hand-wound bicompax chronograph with tachymeter. Movement is the bespoke Seagull ST-1901B (21,600 vph; brand-stated power reserve 50h with the chronograph off, 45h running), regulated in Great Britain to -10/+15 s/day (positions not stated). Case slimmed to 12.9mm with crystal (10.1mm without, per Fratello) from 13.6mm on Gen2; 3-part case, 5 ATM. Double-domed sapphire front and screw-in sapphire display back per Fratello; AR coating and crown type not stated. Ships on a leather strap only; the brand sells an optional stainless steel Milanese mesh strap with buckle (20-16mm, quick-release, GBP 75) for the 01/03SERIES, so bracelet is recorded as not offered. Launch pricing was GBP 550 / USD 650; store price on 2026-10-20 is GBP 600 for all four core colourways. No weight published or found.
