Some early watches, made before the Omega take over have a date stamped on the mechanism.The company changed hands in the 1970s and the new owners destroyed many of the old records, making it difficult to precisely date most Regina watches.The records that still exist make it possible to roughly date them by their serial numbers.

The name Regina Pocket Watch was originally trade marked by LOUIS MAIER in Bienne Switzerland in 1888.

The name was then trademarked by Omega in 1911 indicating that they bought the company at that time.

The faces and mechanisms were imported into New York and assembled with cases in Ontario for sale mostly in Canada.

The National Association of Watch and Clock Collectors describes Regina watches as an inferior brand of Omega, but mentions that some were adjusted highly enough to be used as rail road time pieces, which was the standard for quality watches.

The use of Regina watches for railroad time keeping is documented on other sites as well.

For example: "Some of these Regina-signed watches were Adjusted Highly Enough as to be suitable for use in railroad time service." is sometimes applied to them.

This may be because of their robust quality, the fact that they were sold in rural stores or that Canada had a largely rural population.

Individually stamped production runs were made for a small fee.

The result is that many Regina watches have the name and town of a vendor on their face.

One watch has been traced to the Arcola Jewelry store in Arcola Saskatchewan.

Regina watches are occasionally stamped with the name of an American city, indicating that some were sold in the United States.
