Jaeger-LeCoultre AMVOX

A discontinued partnership line, so it's pre-owned only now. AMVOX was JLC's collaboration with Aston Martin, running from roughly 2004 into the mid-2010s, and it was genuinely inventive: the AMVOX2 chronograph had no pushers at all, you pressed the sapphire crystal itself to start and stop the timing, via a clever vertical trigger. The line also revived JLC's Memovox alarm and, in the AMVOX3, put a tourbillon GMT in what was JLC's first ceramic case (it even had an on-screen turn in Iron Man 2). A distinctive, of-its-era collector's piece for someone who wants something unusual and out of production.
