A lesser known part of the Reverso history: Jaeger-LeCoultre Reverso One

Posted by

Next up in my attempt to make this place more welcoming for the ladies…

I choose to have a closer look at the Jaeger-LeCoultre reference 3352420 Reverso One Duetto Moon in pink gold.

The Reverso One is a line which have it’s roots back in the 1930’s. Yes, the original Reverso were launched in 1931, but the Reverso One is not directly derived from the original Reverso which were made for men

First, let’s have a side-by-side look at the Reverso Classic and the Reverso One. Both cases are 4.10 mm high. While the Reverso Classic is 24.4 mm which gives a ratio (1.6434) very close to the “Golden ratio” (1.6180), the slimmer Reverso One is 20.0 mm with a ratio of 2.005, which gives a more slender look for a ladies wrist.

The very first original Reverso made for men had a similar ratio as the Reverso Classic. Here to be seen in an early 1930’s Italian Jaeger-LeCoultre catalogue.

From the same catalogue – to the left is the normal ladies Reverso but with tube lugs. Ratio similar to the men version. Guess this was the inspiration for the Reverso One Cordonnet…

Now, have a look on the right page, here is a ladies Reverso which have a much more slender look, very similar to the Reverso One!

Unfortunately there is no model name except Reverso, only reference 502 (stainless steel) and 503 (gold).

And while zooming in on the watches, it’s easy to see from where Jaeger-LeCoultre got the inspiration for the Reverso One line, not only for the case but for the dial as well…

The Jaeger-LeCoultre reference 3352420 Reverso One Duetto Moon in pink gold. Front side is very similar to the original ladies Reverso.

The heated blue Dauphine hands differs and so do the dial pattern.

The beautiful sun-ray Guilloché pattern and the engraved case back. Must say I do like the newer models with this ray engraving instead of the circular pattern of previous models.

On the back, there is the mother of pearl Moon Phase. The burgundy red dial brings to mind the Porphyry dials Jaeger-LeCoultre used in the 1970’s. If you missed it, you can read about it here: Jaeger-LeCoultre: “Lapis dial” or “Scale dial” – what is what?

A beautiful balanced dial with subtle gold details and lines which connects very well to the front. And of course, 28 brilliant cut diamonds!

Another detail I really appreciate is the curved case back! Same as the original Reverso, newer models have a nice curve of the lugs which makes the watch embrace of the wrist in a much better way than if flat.

Yes, already in the 1930’s there were a special Reverso case shape for the ladies… And since 2016 it’s finally back in the Jaeger-LeCoultre catalogue!

Big thank you to my local Jaeger-LeCoultre AD Nymans Ur for letting me handle this beauty!
