Hi David, nice challenge indeed! And a tough one indeed to constrain oneself- anyway there we go, in no preferential order:

- Heuer Carrera 510.523 - the L5100 with brushed top, Chuck's favourite and one of my daily wearer, like Rich's indeed I love both, but the PVD one is more delicate, and then it would overlap too much on another one, i.e. ...

- Heuer 510.501 - In the day-date version, this black PVD is one of my all-time favourites of all brands, and the one that led me to far and - once - even unreliable sellers (who proved very reliable in this occasion luckily!). All the Heuer heritage, tachymeter ring, fluted pushers, signed crown, with a good water resistance and a classic shape.

- Heuer Autavia 11063 - the largest Autavia case in the simple black and white layout, two registers with 12-hr recorder.

So here's my 3-only set. It nicely sums up my tastes I think even if it takes out some holy grails like the Siffert.
Cheers,
Fabrizio
