About Me:

"It’s not about having the right opportunities. It’s about handling the opportunities right." ~M. Hunter...

Growing up, handling things right was the only option my mother gave us, and I've carried that with me throughout my online selling career. With 18+ years of experience in vintage timepieces and horology parts, I built my business on one principle: doing things the right way. Inspired by my grandfather, a WWII-era watchmaker, I specialize in vintage watch parts, crystals, and horology books.

Every item is photographed and inspected by me—no stock images, no guesswork. I work to match the right parts for your needs, ensuring accuracy, fast shipping, and honest descriptions. Each order is more than a sale—it’s an opportunity to earn trust.
Thank you for viewing and considering the items I have listed.
