One intriguing aspect of following and appreciating the design of diverse items such as cars, watches, and even something as mundane as spectacle frames, is that you can dismiss, or disregard, things for years on end and then suddenly undergo a complete U-turn.

As a fan of the classic 1950s and 1960s Omega Constellation Manhattan, I had always dismissed Omega’s 1982 reworking of its flagship model, known as the Constellation Manhattan, as something of an aberration from the “true” Constellation concept. Somehow for me it lacked the brand’s recognized “DNA.”

I could see that it lent itself successfully to mother-of-pearl dials and diamanté finishes, so regarded it as more of a ladies’ watch, but felt that it was otherwise something of an outlier in Omega’s range. Its initial production era coincided with the quartz period, which was perhaps another reason for overlooking it.

On top of all that, I have never seen anyone wearing one (apart from my daughter who expropriated the one I bought recently the moment she set eyes on it).

I understand that it has overall been more successful in Asia than in Europe. Nevertheless, the Omega Constellation Manhattan has been in constant production with both quartz and mechanical movements since 1982 in a series of versions that have generally remained true to the original design.

My “road to Damascus” moment occurred recently when I saw a 36 mm black-dial co-axial chronometer on display at an Omega dealer in Bordeaux.

With its dauphine hands it reminded me of my ’64 Constellation, and although I had no intention of buying it I brazenly marched in to try it on.

This is something I am not in the habit of doing: I am in this respect like our friend Agnes, a Bordeaux-based fellow Scot who struggles terribly with the concept of food and wine producers’ fairs in France because she feels that if she agrees to taste even the tiniest sample of cheese or foie gras, she has to buy a large slab of it. I was smitten.

Who designed the Omega Constellation Manhattan?

The design of the Omega Constellation Manhattan is sometimes mistakenly attributed to Gérald Genta; an understandable error as Genta had been involved in the design of various components of the Omega Constellation over the preceding 30 years, notably the “C-shaped” case, which was the “old” Constellation’s final incarnation.

And because the Manhattan’s integrated bracelet, a complete break from the earlier Constellation design, is of course a signature feature of certain other iconic Genta designs.

In fact, the Omega Constellation Manhattan was designed by a young design student from La Chaux-de-Fonds, Carol Didisheim, who joined Omega straight after completing her studies in jewelry design at the Geneva School of Decorative Arts. Omega must have been pleased with its new hire when she came up with such an innovative design at the tender age of 26.

Blogger and Omega Constellation collector Desmond Guilfoyle managed to track down Carol Didisheim a few years ago, interviewing her about her involvement in the design. He learned that she had been inspired by her colleague Pierre-André Aellen’s observation of clasps holding a frameless bathroom mirror to the wall; so rather than using a bezel, the flat crystal of the new Constellation was held in place by four clasps at 3 and 9 o’clock.

This opened up possibilities for printing the hour markers on the underside of the crystal, a slimmer case profile, and improved water resistance.

What is remarkable about Didisheim’s design, which she personally patented in 1985, is that it comprises a set of design features that Omega has allowed to evolve over the years while keeping them true to the original:

Round dial

Roman numerals, initially on the dial but moving to the bezel in 1995, where they have stayed ever since

Four “griffes” (claws) at 3 and 9 o’clock inspired by hooks on a bathroom mirror; originally these ensured water resistance by holding the crystal and gasket in place

Tapered integral bracelet with distinctive link design

Distinctive scalloped case shape, sharp and yet all curves

Over the years, within this design framework Omega has issued the Manhattan variously with baton hands, dauphine hands, day and date subdials, as a perpetual calendar and chronograph, and yet always in keeping with the spirit of the piece.
