History seems to claim that the Ploprof was a hit with the men and a dog with the ladies (not a cute puppy). The design isn't exactly elegant, which has much to do with the fat orange minute hand, and the strange looking asymmetrical case. Today it looks a bit like a Star Wars spacecraft on your wrist. Nevertheless, we find it beautiful. So beautiful that the original models continue to enjoy a very healthy cult status and collector's market. In 2009, Omega released an updated version of the Ploprof under the Seamaster collection, offering fans of the design an exciting modern way of enjoying the famous diver.
Inside the watch is an ETA 2671 automatic movement. This is a small diameter automatic which allows enough space for the traditional music box components. Resonance is an issue in watches like this but the drum and pin set up can be remarkably loud, so I expect that the Boegli Grand Opera has a nice sound to it. The 17 note system plays a melody from Mozart's The Magic Flute. I think something from Led Zeppelin would be cool as well. Boegli will produce only 99 pieces of the Grand Opera watch, which comes with a relatively sober price tag of 3,800-4,200 Swiss Francs.
The Opus 2 - Featuring a 38mm platinum case and a total of two possible versions, the Opus 2 is the result of a collaboration with watchmaker Antoine Preziuso. The Opus 2 was limited to 11 units spanning two different movement options which additionally each had a special single unit adorned with diamonds for a total existence of just 24 hand-made pieces. Seen as both a tourbillon with retrograde calendar or as a fully exposed tourbillon, this auction was for a diamond clad version of the latter and saw estimates of 0,000 - 5,000. This extremely limited piece found a new home with a hammer price of 1,318 USD (lot 4581).
