For me small Zenith sign on the case back and unmarked crown.

 

Thanks for that.

Small sample taken from sales, chrono24 and google. Pretty sure I haven't double counted.

No obvious correlation between sign size and crown markings but if this very small sample is representative then it does show how many de Luca mk 1's there are out there with marked crowns!

Unmarked - 5
Marked - 7

Would they all be service replacements. No, IMO. Although I personally like the unmarked crown!

Equally as many with large signs as small signs but no link with crown type.

 

Mine has the large logo on caseback and unsigned crown.
In Italy, where these were all originally sold, the widespread opinion is that the original crown is UNSIGNED.
I am speaking about MKI.
This is based on the fact that several NOS model have been found in the past few years, with box and papers and still sealed, and all had unsigned crowns.
It would be interesting to see if there is correlation between white vs silver subdials and big vs small caseback logo.

 

You have a great collection there. You clearly see the evolution of the design from the A277 to the MK1 de Luca. Personally I'd prefer the A277 and yours is a superb example.

 

Small logo and unsigned crown, I have just recently purchased my Mk1 it needs a full service I'm thinking of sending to Zenith has anybody had any experience of servicing with Zenith? will they only replace the parts I ask them too?

 

@WillsA so mine has a small logo and a signed crown and silver subdials @Mlafra

 

Very nice watch, in my opinion Zenith compete with Omega watches very well. And for me, forgetting that the Rolex is more expensive, it's not so good looking as those.

 

Here is my 01.0043.400:

 

been following these since many years and it seems the last yer or so they become much more expensive. The first series was between 3500 and 4000 about 1-2 years ago.
Today They are 6000 - 7500

Such a rare and beautiful watch ... I think in the future they will become very hard to get and a lot more expensive

 

Great Collection @Adri - wonderful!

Zenith is somehow addictive: Highest Quality, great movement, Individual design - for me a sort of „Swiss Army Knife“ of watches

My De Luca II: Diver, Panda, Chrono, Automatic - El Primero = Full Score

 

Mine is a frankenwatch. Should be a MKI like to one from westmoth. But has the MKII Dail and a wrong hour hand. Small logo and marked crown.
Apparently there was a tinkering at this clock. Therefore, that is not meaningful.

 

I have this.... yes I know, but it is no bad as is.

I have just spotted this
Mine is Mk 1 small logo on the back, unmarked crown.



Given the stratospheric rise in some chronograph values recently (Heuers of all types and Lemania miitary ones for instance) I would also like to add that De Lucas still represent great value today. As of now there are 14 De Lucas on Chono24, 5 priced under £4k, and every one of them under £7k. By comparison there are over 120 Autavias priced above £7k, making them not only a lot more common, but also overvalued.

Congratulations!

 

In short, and to paraphrase the Squirrel, NFW!

 

Beautiful watches!!

 

Heres my mk1. I hunted it for a couple of years and wanted one in great condition and also wanted the bracelet for it. thanx for cool and intresting thread of a really cool watch!

 

here's mine!
I love it!

small logo on caseback!

 

Got my De Luca back today from watchmaker. Zenith delivered NOS Tritium parts to get back the original state as 1 of 375:
