It is nice to be able to have this kind of deliberation going on, especially when you want to trade in the watch you like but do not love
- most of us have been down that road before (what an exciting and thrilling state of mind to be in!)
I say you do what your heart tells you! It's always the best way to be... I am sure if you're tempted by the watch just go for it. It is a great timepiece with a different movement, different complications as well as made out of different metal from the one OS you already have. So that differentiation factor plays in favor of the purchase.
I'd considered the OS Dual Time myself before my all-time favorite OS the US limited edition Chrono came along. I do not necessarily find YG attractive, but hey that is just me. If I were to make that decision, I would certainly consider other options i.e. SS/Ti OS models (they are very masculine, stealthy - definitely man-oriented pieces IMO) or wait for next year's SIHH novelties' uncovering. Maybe, just maybe VC will decide to introduce new metals to the OS line, like full titanium or tantalum? Who knows...
Anyway, if you travel a lot, here's a good tip to use your chrono VC to time the second time zone on your OS. Once you adjust the time on your watch to the local time, make sure what time difference there is between your local geographical position and let's say your home base. Say the time difference is 6 hours ahead. Start running your chrono at 6 am or 6 pm. If you keep on running the chrono function it will indicate your actual home time. 12-hour totalizer plus the 30-minute totalizer do that just fine, don't you think? The only drawback to this solution is that the watch won't tell if it's night or day but hey you can just tell by looking out the window, right. I have to tell you, once I made that revelation on my OS I decided never to buy a dual time watch for myself since the OS is my weekender/vacationer. It would have to be an exceptional design to make me reconsider...
Anyway, good luck on your hunt and decision!
