Finally got to see the Caliber 1003 of my Patrimony Extra Thin. I took

both my VC's to the VC Doctor at the ION Orchard Boutique today; while my Traditionelle passed with flying colours, the 90's extra-thin needs to go for servicing. However, VC's Resident Watchmaker removed the solid caseback so I could see the beautiful movement.

Nice juxtaposition with the 4400

Phone camera?  I think Dan has some gadget that really sharpens those iPhone shots.  Say, those movement models would sure make a great draw prize!!

Its actually a Loupe made by a very good friend of mine.

He also makes cases for the iPhone that allow you to use the loupe as a macro lens in order to take some really nice close-ups with an iPhone.

I love the large scale models of these movements, but I've been told they cost as much as their actual I don't think it will be available for prizes (though I SO want one!)

Yes phone camera. Best I could do without the VC staff thinking that I

have completely lost it.

As fine as great movements go!

Has the 1003/2003 ever been reviewed
05/27/2015 - 15:22

by a celebrity watchmaker like Kari?  I'd love to know from a technical perspective both the compromises and highlights of this ultrathin icon.

I think 2003 was reviewed somewhere on The Purists a looooong time ago but

can't seem to find it anymore.

Found something on the beginnings of the cal. 1003

I'm still off-balance from your new watch teaser but want to get this off my do-do list.  An article in Feb 2014 issue of Revolution on AP's ultra-thin calibers provides some fascinating background.

The writer, Martin Green, states that it all began in 1938 when AP introduced a 9-ligne ultra-thin manual movement called 9'''ML (or 9ML if you Google).  Interestingly, it was 1.64mm thick enlightened.  After fifteen years in production for wrist and coin watches, AP starting looking for a replacement and teamed up with VC to approach Jaeger-LeCoultre for the a re-design of the 9ML and subsequent manufacture.  JLC's resulting 803 retained the height and width of the 9ML, but reduced the number of bridges to improve durability.

Because AP provided the base design for the project, they also retained exclusive use of the new movement, named Calibre 2003, for two years beginning in 1953.  VC, as we know, introduced the Cal. 1003 in 1955.

Some internet sources indicate that the 9ML was itself adapted from an earlier and larger pocket watch movement by Frederic Piguet.  When AP purchased the design, they updated the winding and setting mechanism, the so-called keyless works.  When JLC became involved in the later re-design, aside from the reduction in bridges, they also integrated a newly developed keyless works which was significantly sturdier.  Production stopped in 2002 and AP discontinued the movement but VC persevered using available stocks until it brought manufacture of the 1003 in-house.

All-in-all, the movement takes even more significance for me, aside from its physical properties, as a great example of the collaboration that existed within the Swiss watch industry.


fascinating Dean, thanks so much!

I did not know this history of 1003/2003 and thought it was designed from scratch.  No idea about the 9ML before, terrific info!

An interesting 'top up'...

Thank you Dean for the additional research. Much appreciated!
