Collector's Weekly has a wonderful series of interviews which they conduct every few weeks with various people in the vintage collecting field. Many of these are jewelry related.
The latest interview is with Jeff Stein, a collector of various watches, particularly chronographs. Jeff is the operator of a leading online guide to Heuer chronographs and timepieces.
Jeff originally started collecting watches because of his interest in racing and vintage rally cars. At an early 1960s rally, he discovered another visitor with a display of Heuer timepieces, and he was hooked.
In the interview, Jeff discusses all types of chronographs and Heuer in particular. You can read the full interview on this page of the collector's weekly website.
