Thanks to the precise archive work by Fred Mandelbaum, we know that there are four different Mks. Each one has a very specific setup, differing only in small details that might slip past the untrained eye.

Fake Breitling 765 AVI Lucy Digital Mk1.1
In March 1953, the first 50 cases were assembled. This was just before perfect replica Breitling moved its headquarters to Geneva, so the dials are “pre-Geneve.” The fully lumed chrono seconds hand is unique to this execution, and it is combined with the slim, lumed syringe hands that we also see on the Mk1.2.

This was manufactured between late 1953 and 1956 after luxury fake Breitling had moved its headquarters to Geneva, so dials have the “Geneve” stamp. The richly lumed central chrono seconds hand was changed to a white hand with a teardrop-shaped lumed tip. As mentioned before, a correct Mk1.2 should have slim, lumed syringe-style hands for hours and minutes. The movements are marked “BOW” for US exports or carry no import code.

Swiss movement fake Breitling Mk1.3 was manufactured between 1956 and 1959, and its dials are marked “Geneve” too. The teardrop-shaped lumed chronograph seconds hand is combined with wider lumed syringe hands with a shorter “needle” on the hour hand. The movements are marked “WOG” for US exports, or they carry no import code.

And here comes Fred again, who helped me understand why my 765 Lucy Digital is a Mk1.4. The bezel on the Mk1.3 has 126 small beads, as do the Mk1.1 and Mk1.2. In 1960, AAA quality replica Breitling UK fitted the 765 Lucy Digital with a similarly configured Mk1.4 bezel, but it “only” has 96 larger beads. There is a Lucy Digital listed on Chrono24 at the moment for a beefy €23K tag, but it’s fitted with a 765 Mk2 bezel. From the top, it might appear to be correct, but upon closer inspection of its coin edge, we see that it doesn’t belong to Lucy Digital at all. Be careful.

In love with the digital 15
Back to the design. Honestly, the idea of the digital minute counter blew my mind. I’ve always wondered why there weren’t more watches like that. I find reading a chronograph minute counter a bit tricky sometimes, especially if I don’t have much time or my attention needs to be somewhere else. For example, think of trying to read the elapsed time quickly while driving and keeping full attention on the traffic ahead. In such a situation, you will hardly find a more legible solution to ensure quick and precise time reading.
