Editorial
The IW371446 is the watch that defined the Portugieser Chronograph for a generation of collectors. It ran for over two decades as reference 3714, long enough to earn genuine secondary-market depth and a clear collector consensus: silver dial, blued hands, no date. The Valjoux 7750 base gets a hard look from purists, but the column-wheel modification IWC added earns real respect from people who know what they are looking at.
IWC launched the modern Portugieser Chronograph in 1998 and built the 3714 generation around caliber 79350, a column-wheel-modified Valjoux 7750 with an IWC finishing module. The 41mm steel case ran essentially unchanged through 2020, when IWC replaced it with the 3716 generation on the in-house caliber 69355. That 22-year run produced meaningful variation in dial texture, hand finishing, and case brushing across production years.
The silver "Ardoise" dial with applied indices is the most-sought configuration; panda layouts were offered in limited runs. The 3716 replacement triggered a wave of 3714 buying as collectors locked in the outgoing reference before prices moved.
Chronograph pushers on the 7750 base take wear before the going train does, so verify the start-stop-reset cycle works crisply and resets to zero without a jump or stutter. Dial condition matters more than usual here because silver dials show moisture damage and hairlines around the sub-register printing readily. The date window version (IW371480) shares the same generation and is sometimes listed without clear differentiation, so confirm the reference number matches the no-date dial you are targeting.
Case polishing is rampant on dealer pieces: check that the lugs retain their original geometry and the pump pushers have not been rounded. Service history documentation is worth asking for specifically because a 7750-based movement at 20-plus years without service is overdue.
