Reardon began link collecting these rare pieces as well, obsessed with all things Patek and inspired by seeing his first electronic master clock at Patek Philippe USA when he started link working at the Henri link Stern Watch Agency in 2001.

Now, if I told you that a link career mechanical engineer decided to try his hand at watchmaking, obtain a degree in the subject, and change careers, you might not link think that is too far fetched. But what about a mechanical engineer whose focus, for link nearly 25 years, was in missile and spacecraft attitude control systems? Now that career move would be wild. Well, that is precisely what Jerry Tate did, and his journey in doing so is nothing if not interesting.
