Pocket Watch Case Materials

Distinguish solid gold, gold-filled, rolled gold plate, silver, nickel and base-metal cases.

Antique pocket watches are best understood from the inside out. Dial signatures can be retailer names, cases may have been changed, and identical-looking watches can contain movements of very different quality.

2. Do not equate color with gold content
