While Sotheby's Important Watches Sale in Geneva taking place tomorrow May 14, 2014 won't be as big as the Christie's sale, it for sure will have some wow factor coming from 23 lots that we will be following very closely. This upcoming sale taking place tomorrow in Geneva, includes 342 lots divided in two sessions:

Session 1: 14 May 2014 | 10:00 AM | Lots 1 - 160
Session 2: 14 May 2014 | 2:00 PM | Lots 161 - 342

With almost 100 lots less than Christie's Important Watches Sale, this auction includes some extraordinary timepieces based on their historical importance as well as their rarity. As with any auction, the usual suspects are present including a nicely curated selection of vintage timepieces from Rolex including several Paul Newman Daytonas, early Submariners, Double Red Sea-Dwellers and a couple Milgauss watches. Additionally, there is a wide selection of other timepieces from other brands ranging all the way from Patek Philippe to Audemars Piguet and Vacheron Constantin, to IWC, Cartier and everything in between. Regardless, without a doubt, the attention will focus on ten lots in particular that will for sure fetch very large sums of money.

1. Patek Philippe Minute Repeater with Perpetual Calendar Retrograde Date and Moon Phases ref. 5013 —Lot 160.

2. White Gold Patek Philippe Perpetual Calendar with Moon Phases ref. 3448 —Lot 340.

3. Rolex ref. 6062 Triple Calendar with Moon Phases and star dial —Lot 342.

4. Rolex ref. 3525 Chronograph with Telemeter and Tachymeter retailed by Verga —Lot 300.

5. Extremely rare Panerai Mille Metri prototype in titanium circa 1985 —Lot 295.

6. Extremely rare and historical Panerai ref. 6152/1 with prototype bezel and crown guard circa 1955—Lot 298.

7. Rolex Paul Newman Daytona ref. 6239 circa 1969 with chrono registers that have faded to a very nice chocolate brown color—Lot 305.

8. Full-set Rolex Paul Newman Daytona ref. 6263/6262 circa 1972 —Lot 341.

9. Rolex Submariner ref. 5513 MilSub circa 1972 —Lot 244.

10. Platinum diamond-set Rolex Day-Date ref. 1804 with turquoise Stella dial circa 1976 —Lot 131.

In addition to these ten exceptional watches, we believe that six other lots will also experience special interest from watch collectors around the world. These include two ultra rare Rolex ref. 5100 Quartz watches in yellow gold and white gold respectively—Lot 219 and 220—, a LeCoultre Reverso with red lacquer dial circa 1931 —Lot 251—, a full-set Audemars Piguet Royal Oak Offshore 'End of Days' Limited Edition case number 154 of 500 and lastly, an early Audemars Piguet Royal Oak Offshore ref. 25721ST circa 1995 with case number 322. This particular Audemars Piguet Royal Oak Offshore recently became a must have for Audemars Piguet watch collectors as the traditional Royal Oak Offshore model was redesigned and released at the SIHH 2014 back in January. This Audemars Piguet Royal Oak Offshore ref. 25721ST with blue dial is an early example of perhaps 500-700 Offshores like this one ever made.

In addition to the 15 lots highlighted above, there are eight other lots that should also be followed considering the importance of the watches and their highly collectible nature. Below you will find these lots.
