At Blancpain, thirteen generations of watchmakers have passed down their creativity and expertise for more than 250 years. This heritage is also an integral part of every Blancpain timepiece, making it a precious object to be passed down from generation to generation.

Svend Andersen, co-founder with Vincent Calabrese of the AHCI in 1985, has done more than most to keep watchmaking alive as an art in an era ruled by the dead hand of the brands. Andersen, like Calabrese, is one of those natural mechanical geniuses for whom anything is possible. Born in 1942 to a Danish smallholder, Andersen was apprenticed to a watchmaker in Padborg on the border with Germany (most of the work consisted of replacing broken balance-staffs of pre-Incabloc watches), and gained his watchmaking diploma at the Royal Danish Technical Institute. Designs are quite unique.

In 1989, Accurate Watches were introduced in Bienne, Switzerland. The company had decided that although profits were important, it would focus on producing fine Swiss-made watches to sell at prices that would encourage retail customers to wear a Swiss watch because it was affordable. The correctness of the decision was reinforced when the ?USA Today? published a survey on attitudes about purchasing Swiss watches. Watches made in Switzerland, the survey reported, are considered: “high quality,” “fashionable,” “expensive,” ” status,” and “want friends to see.”

Senior Lecturer (UT Austin) – Gem Notes for Accompanying Lecture
Nice explanation of basics in gemology and easy to understand for most interested lay people. Each of the gem summaries is divided into several sections. After a brief introduction that defines precisely what the gem is and the gemological names that are used to describe it, the physical and optical properties useful for identification are given. In compiling these data, I relied heavily on the book by Anderson, and to a lesser extent the recent book by O’Donaghue. Pricing information at the bottom of each gem page are out of date.
