As discussed in an earlier thread , Daniel Roth offers a dual timezone watch in its Masters range. This model, the Metropolitan, is an evolution of the now discontinued Vantage model. Unlike most dual time watches, the Metropolitan offers a Daylight Savings Time (DST) function, amongst others. A summary of its functions (bold text from Daniel Roth press release, italics are mine):- Hours & minutes in the center- Hours hand for the time zone of reference (home time)- Indication ...

The new watches unveiled at Baselworld have gotten everyone's attention. There are watches already in the collection that are equally deserving of attention, like this 8-days tourbillon in platinum, which just arrived at an authorised dealer yesterday.This is the first time I handled this particular model in platinum, previously I had only seen it in rose gold and white gold.

The Daniel Roth Papillon is available in rose or white gold, and platinum. Recently I had the chance to photograph a specimen in platinum; it was a truly solid chunk of platinum. Here it is in comparison to a Metropolitan dual-time in white gold. Both use the same ellipsocurvex case, which has a curved caseback. I do like the heft of the platinum Papillon and the deep metallic blue of the dial is very eye-catching. But I still prefer the richer colours of the rose gold ...
