Horological Meandering - May I offer a clarification?

May I offer a clarification?

In fact, Ebel's cal. 137 movement is the result of a team project of Ebel and Ulysse Nardin to develop a chronograph movement for one, and a perpetual calendar movement for the other. The Lémania 1340 design was acquired by these two companies, and Nouvelle Lémania (later Manufacture Breguet) reserved the right to use it for own purposes. Main point of interest behind the acquisition was the Lémania's Pellaton system for the bidirectional automatic winding mechanism, permitting a thin design and higher integration of the complication.
For more details, please see this old article:

So when Ulysse Nardin acquired the Ebel cal. 137, not only the plans and all tools, but also all spare parts were part of the deal. When I visited the UN factory several years ago, I saw that UN had also took over the service of the Ebel chronographs, but I do not know if this is still the case.

A blast from the past - Ebel 1911 Btr

or how I detected a “new” brand for me: After collecting wristwatches for more than 13 years I thought I have seen and - fast - owned everything. In this Summer I went for a watch what I bought without seeing it in the flesh and while I was in the shop I ...

Fantastic find Adam! Yes your pictures omit the Cal. 134 based on....

a Zenith movement some of us may have heard of. 😀 That's a looker if you ask me. Hard to believe it sat in the case unloved for so long. Congrats!

Are you sure it is still the Primero movement?

I think the BTR line already had the "Modulor" cal. 137 movement, which was an own Ebel development, based on the Lémania 1340 (with center minute counter, but Ebel wanted to continue the classic Tricompax layout of the Primero). This great chronograph mo...

You could be correct---

---- the "Modulor' movement is certainly used in the 1911 chronograph line and is based as you said on the Lemania regards the BTR line,it's likely too.I was also looking for the El Primero version. Mine shown here is based on the Cal 137 movement ...

No, I'm not sure. I thought they used the El Primero as a base in this one too. Thanks for the clarification Marcus.

Many thanks for your responses, Mates!

Marcus has right: the movement is a Base Lemania 1340, which is modified and personalized by Ebel. Remember, that the same base movement was used by Omega ( Speedmaster ) and by Breguet ( Type XX and XXI ), the later were equipped by a flyback function. M...

love mine too... I agree with your review

I especially appreciate the larger seconds register at 9:00, separating it visually from the chrono registers. Don't see that too often on current chronographs. Some days, feel like a hefty watch with great movement and classic look, this fits just right....

Dear Rock,

By: Speedie74 aka Mr. Torquise : September 23rd, 2021-05:08

yes, that’s why - for other reasons as well - I love this watch: the subdial of the little second is different from the other subdial’s size. VC has made the same solution at the second generation Overseas Chronos, I am not sure which came first, the chic...
