The BG169R-8 doesn't allow for such capability. In those picture-in-picture sequences, it appears we aren't seeing the same dial as the watch on Nancy's wrist. Oh, the magic of movies. Six months later, the brand introduced the new 9RA2 movement with five-day power reserve in the SLGA007 and SLGA008, moving the power reserve to the movement side of the watch and resolving a pet peeve of GS Spring Drive fans. New York collector Michael also brought the double-wristed heat — Zeitwerk Date and Lange 1 Onyx Dial.

Some people will swear on their deathbeds that the Berenstain Bears kids' books were about the Berenstein Bears, for instance. I said that the Benrus Type 1 was a Proustian madeleine for me, but there is no Type 1 in my childhood past. As you may well imagine, the estimate for this watch runs into the seven figures on the high side – £700,000-1,000,000, €805,000-1,150,000, US$895,000-1,280,000. This seems merely reasonable given the performance of other Breguet four-minute tourbillons at auction (not that the sample size is very large), but I would not be surprised to see a stronger result, for obvious reasons. Fake Panerai Luminor Before Rolex introduced the Explorer, Submariner, and GMT-Master, it wasn't even that uncommon to see white or silver dials on its early '50s sport watches: Edmond Hillary's Everest Rolex that served as inspiration for the Explorer had a white dial; so did early examples of the Turn-O-Graph, the Submariner precursor; even Deep Sea Special No. On top of that, Vacheron's heritage and style director, Christian Selmoni has said on several occasions that there is no evidence whatsoever in Vacheron's archives to support the supposition that these were intended to be driver's watches. You can argue (and the dear Lord knows people do) that functionality and its handmaidens, accuracy and legibility, should be the primary raison d'être of any watch but this is not the case often enough for it to be worth noticing.

The vintage inspiration of the 5170 is clear, perfectly punctuated with the pulsation scale.

He has also worked on a number of freelance special projects over the years and in a marketing/PR consulting capacity, for clients both within and outside the watch industry.
