Catalogue Note

With an Extract from the Archives confirming sale with diamond hour markers on 16 October 1964,  original tie tag listing the original retail price of $2175.00, and original Patek Philippe fitted presentation box and outer packaging.

The present lot is an extremely rare platinum example of a reference 3445 with a diamond dial, and is being offered in exceptional condition. According to our research, fewer than 10 examples of Ref. 3445 in platinum are known to the market.  

The watch is being offered in essentially new-old-stock condition. It retains a crisp, flat bezel with non-polished edges. The watch is further accentuated by the well defined faceted lugs that are a key characteristic of the 3445. These lugs still retain elements of the plastic that originally wrapped the watch upon delivery in 1964.

The present lot has been in the possession of the original owner since its purchase from Patek Philippe in 1964, and this is the first time it has been offered at auction.

Ref. 3445, frequently referred to as the 'Monodate', was the first calendar wristwatch produced by the company in series. It was manufactured from 1961 until 1981.

Cal. 27-460M and Ref. 3445 are illustrated in Huber, M. & Banbery, A., Patek Philippe Wristwatches, Vol. II, Second Edition, pp. 220-221.
