In showcase 64 of the Patek Philippe Museum, entitled "The Second at the Center", sits this magnificent watch with a two-tone sector dial signed β€œSomazzi Lugano”.



The movement was manufactured in 1919 and the case in 1934.









As shown by these pages from the two museum catalogues I have, this is a reference 96 SC (for Second at the Centre).



And the case is made of a β€œnon-corroding steel alloy marketed as β€˜Staybrite’”.



Other ref. 96 from the same period with the exact same sector dial can be found, like the following one, which dates from 1935.





Or this one, also from 1935, with a dial signed with the name of the Milanese retailer Hausmann & Co.

This iconic two-tone sector dial was obviously the source of inspiration of the modern ref. 5296G-001:

I could of course end the post here. But I prefer to delve a little deeper by researching who Somazzi is and whether there are other pieces whose dial is also signed β€œSomazzi Lugano” or other important collaboration pieces.

Well, first, Orologeria Somazzi was founded in 1860 by Stefano Somazzi and it is a family business that has been selling, repairing and restoring watches ever since.

It has retailed Patek Philippe timepieces since 1906.

I have been able to find several watches with a dial signed β€œSomazzi”, but none except one with a dial signed β€œSomazzi Lugano” like the example of the Patek Philippe Museum.

This exception is the following ref. 130, which, according to Antiquroum, was made in 1937, delivered to E. Somazzi, Lugano, on December 2, 1937.

The image is of very poor quality, but the dial seems to be signed β€œE. Somazzi Lugano”, Emilio Somazzi being the son of Stefano, who took over the business in 1892.

Here are other examples with only β€œSomazzi”.

A ref. 570 with unknown date:

And a ref. 3548/1J from 1972:

Finally, in 2010, Patek Philippe celebrated Somazzi's 150th anniversary with two special versions of the ref. 5296.

Both were limited to 15 pieces, each bearing the following text on the sapphire caseback: β€œ150 anni Somazzi 1860-2010” as well as the number β€œxx/15”.

White gold ref. 5296G-013





Rose gold ref. 5296R-012

About the Patek Philippe Complications Ref. 130

The Patek Philippe Reference 130 is a significant chronograph model, notable for its classic design and the various configurations in which it was produced. While many examples feature a standard chronograph layout, specific iterations, such as those with split-seconds functionality, represent a higher echelon of horological complexity within the reference. The model is recognized for its balanced proportions and the legibility of its dial, making it a favored choice among collectors seeking vintage Patek Philippe chronographs.

This particular example of the Reference 130 is distinguished by its yellow gold case, measuring 33mm in diameter. It houses a manual-winding movement, typical for chronographs of its era, and is fitted with a crystal, likely acrylic or sapphire depending on the specific production period and any subsequent servicing. The case construction and movement finishing adhere to Patek Philippe's high standards for precision and durability.

Collector interest in the Reference 130 is driven by its historical importance as an early chronograph from the brand and the rarity of certain dial and complication variations. The presence of unique characteristics, such as Breguet numerals, specific dial signatures, or the absence of a tachymeter scale, can significantly influence its appeal. The reference appeals to those who appreciate the foundational designs of Patek Philippe's chronograph lineage.

Thanks for the wonderful post, Emmanuel!

The sector dials got me thinking about this one which is a very close copy ( the dial, hands and even the case). This is my TZ 21st anniversary edition from 2017. I have loved it since then 😁. I need to pull it out of the bank vault so I can enjoy it all over again.

Thanks Emmanuel for the post with such intersesting history ! Sector dial is an interesting design !

Many years ago when I saw reviewing Calatrava AR models, the 5396 sector dial drew my attention. I liked the overall design but at the end felt that with an AR function, the dial was too busy for my taste. 5296 on the other hand strikes a very good balance. Given Patek worked with many family owned retailers in the past, I wonder how many of them was able to have dials double-stamped ?

I agree with you that the sector dial of the 5296 looks better than the one of the 5396.

Concerning the double stamped dials, I have listed around 30 different brands: I will post about it soon. Best, Emmanuel
