Amazon.com, Inc. said the 2008 holiday season was its best ever. However, the online retailer did not release sales figures.

The Seattle-based company said it received more than 6.3 million items ordered worldwide on its peak day, Dec. 15, a record-breaking 72.9 items per second.

Amazon Worldwide includes www.amazon.com, www.amazon.co.uk, www.amazon.de, www.amazon.fr, www.amazon.co.jp and www.amazon.ca.

Amazon listed its most popular jewelry and watch items for the seasons.

Jewelry top sellers included a 14k white gold Journey Curve pendant (1/2 cttw, H color, I1 clarity); the platinum, round, diamond 4-prong stud earrings (1 cttw, G-H color, VS2 clarity); and the sterling silver marcasite and garnet 18-inch glass heart pendant.

Top-selling watches included the Invicta men’s Pro Diver stainless-steel watch, Citizen’s Eco-Drive men’s Chronograph Canvas watch, and Movado’s Juro stainless-steel watch for men.

In addition, the company said it sold enough Casio G-Shock watches to outfit every Kanye West fan attending the 2008 Glow in the Dark Tour concert at New York’s Madison Square Garden.
