Why I bought it

I usually don't buy quartz watches, but this one was impossible for me to resist. First came the design, then the Gianni Bulgari story, and then I discovered that it was a Dahl Bi-Time, one of his most interesting jumping-hour designs. But the real surprise came later: the Omani Khanjar engraved on the caseback and, even better, the original presentation card showing that the watch was commissioned as a gift by Sultan Qaboos bin Said. Add the surprisingly sophisticated mechanical jumping-hour module sitting on top of an ETA quartz movement, and this became one of my favorite jumping hours in the collection. Beautiful, unusual, historically interesting, and being quartz, a perfect daily watch.

A Gianni Bulgari GB Enigma “Dahl” Bi-Time jumping hour from the early 1990s, serial no. 800. Powered by an ETA 955-series quartz base movement, it uses an unusual proprietary mechanical module to operate the jumping-hour display.

This example is particularly special. The caseback carries the crowned Khanjar of Oman, and the original set includes a presentation card stating that the watch was made “By Special Order of His Majesty The Sultan Qaboos Bin Said Al Said,” with regards from the Minister of the Royal Diwan.

I don't usually buy quartz watches, but I loved the Dahl's unusual horseshoe design from the moment I saw it. After discovering the story behind it, it has become one of my favorite and, in my opinion, most beautiful jumping hours. See the Journal for more details: read more in journal
