There isn't a WUS forum for watches like this - and in case someone says so, it does not belong in 'Fashion Watches'.
And the ana-digi aspect is interesting, and anyway, I live here and Bluegum asked for pictures.
Dunhill. A British equivalent to Cartier, but now, like Cartier, part of the Richemont luxury group along with Jaeger Le-Coultre and IWC. Dunhill has been designing watches since the turn of the twentieth century. Designed in London but made in Switzerland (these days by Jaeger Le-Coultre, but I don't know who made this one).
Faceted crystals have been a feature of Dunhill watches since the 1930s, and echo the design of the interior lamps that Dunhill was then providing for Rolls-Royce. Art-deco references aside, you could call the D7 a nerdy dress-watch - a thinly-populated category that might also include the ana-digi models in the Rado catalogue (which probably have the same ETA movement, also shared with early Breitling Navitimers and, more prosaically, some Tissots).
These pictures (borrowed from Upscale Time, one of the companies selling old stock) show most of the displays:
I don't know how this will fare in my collection in the long-term - it's just too different from anything I've had before. I know one thing though - it will help suppress the temptation to brandish my credit card in the direction of a four-figure Rado. Nah, too flat, those Rados. Facets, man, that's what you want - facets.
It's the facets that make it. The DM7 is a fully-fledged chronograph with two stopwatches (both 24hr), countdown timer (24hr), dual time and alarm (all operated from the crown), but it's the faceted crystal that gives it a whiff of ritzy Mayfair, circa 1936. It also helps send the digital display into inky oblivion should you choose to switch it off. Quite a masterful piece of design really. The crystal is curved as well as faceted and must be pretty thick to allow for both. The effect is of a jewel in a brushed-steel frame, and it presents a different face from every angle. An anti-reflective crystal would be missing the point on this watch...
The Mondrian effect -
Downsides? Switching modes and making adjustments is fiddly compared to a four-button chrono like a G-Shock. And if it's dark you can't see the hands or the digital display. Doesn't matter though - lumed hands and a backlight (and a backlight button) would ruin it.
The retail price for these was a tank of petrol short of £1,000, but new old stock is currently available for much less (the result of a 'mechanical makeover' at Dunhill), and I paid much less than that. I'd admired the design for years but had assumed they were expensive. Seeing one for sale on TZ-UK for G-Shock money... well, it was a simple decision.
Bring the car round to the front, James - we're off to Claridges for cocktails.
