On my recent trip to Singapore, I purchased a DeBethune DB9 in white gold. I didn't know much about the brand, but I was always a fan of their clean designs, and classic guilloche dials. This particular one comes with a gold dial finished with blue arabic numerals, and beautiful blued hands.
The moonphase is acually an indicator for the 7-day power reserve. A big watch at 42mm, its slim profile makes it a very attractive watch to wear with a suit.
Here's a quick and dirty pic of the watch, with all its guilloche glory.
