Sotheby's sale of Important Watches, Clocks and Automata will be held on 20 October, 2009.

The auction features a wide selection of modern and vintage wristwatches, ladies' wristwatches, pocket watches and clocks.

The sale is estimated to bring in over $2m and will be on view at Sotheby's New York headquarters beginning October 14.

Sotheby's sale will once again include a fine selection of modern and vintage watches by Patek Philippe.

These will be led by an 18K Yellow Gold Perpetual Calendar Wristwatch with Moon-Phases, dated 1949, Ref 1526J, estimated at $70-90,000.

Together with reference 1518, reference 1526 was the first perpetual calendar wristwatch produced in series by any company.

With just over 200 examples produced, this is a rare appearance on the market.

A Patek Philippe fine and rare Wristwatch with Cloisonné Enamel Dial in an 18K Pink Gold French Case, dated 1949, is also included, estimated at $30-50,000.

Patek Philippe wristwatches with cloisonné enamel dials are widely sought-after. Full enamelled dial plates, like this one, are considered the most desirable among collectors.

Three Patek Philippe reference T-150 wristwatches will be offered.

The T-150 was created in 2001 to commemorate the 150th anniversary of the relationship between Tiffany and Patek Philippe.

Its production was limited to 150 pieces in each of three metals: white, yellow and pink gold.

Tiffany was the first retailer of Patek Philippe in America, and the two brands continue to enjoy a flourishing relationship today.

The October auction will include two white gold, and one pink gold, examples of the Automatic Sweep Seconds Annual Calendar Hinged Wristwatch with Moon-Phases, all dated 2001.

Their references are 5150G T-150 ($30-40,000 each) and 5150R T-150 respectively ($25-35,000).

A fine and rare Platinum Flared Rectangular Wristwatch with Diamond Indexes by Patek Philippe, dated 1951, Ref 1593P will be going under the hammer at $20-30,000.

This model, launched in 1944 and is commonly called the 'Hour-Glass' due to its flared shape, and is among the most desirable 'hour-glass' examples available to collectors.

The more unusual timepieces by Patek Philippe include a Lady's Rare Art Nouveau 18K Yellow Gold Enamel and Pearl-Set Pendant Watch from 1901, estimated at $7-9,000.

The clocks on offer include a Rock Crystal, Gold and Enamel Diamond-Set Wandering Hour Clock attributed to Cartier, circa 1920 ($40-60,000) and a Rock Crystal, Gold and Enamel Diamond-Set Strut Timepiece, also by Cartier, circa 1920 ($20-30,000).

This piece is an extraordinary and particularly rare example of the beautiful works created by Cartier in the late 1910s and early 1920s, drawing on the firm's tradition of elegant jewellery designs.

The sale will also include a selection of vintage and sport Rolex watches.

These are highlighted by a Stainless Steel Automatic Sweep Seconds Wristwatch with Date and Bracelet, retailed by Tiffany & Co, dated circa 1968, Ref 1680 'Red Tiffany' Submariner ($25-35,000).

The 'Red Tiffany' is extremely unusual, featuring the Tiffany & Co signature in red rather than the 'Submariner' mark in red, as most examples appear. It is the only example to come to the auction market in recent years.

Among the pocket watches on offer is a Rare Gold and Enamel Musical Watch with 'The Music Lesson' Automata by Piguet & Capt, circa 1815 ($40-50,000).

An H. R. Ekegren 18K Yellow Gold Hunting Cased Minute-Repeating Split-Second Chronograph Watch with Date and Enamel Family Portrait signed J. Graff, dated circa 1885, will also be highlighted ($8-12,000).
