Family member gave me this pocket watch. Been trying to figure out what it is but can't find much online.

- Says "THE GRENWICH CANADA" on the movement and dial
- 15 Jewels Adjusted Working and ticking
- Case has floral engraving Case stamped "GUARANTEED EXPRESS 20 YEARS"
- Serial number looks to be 124987

Tried pocketwatchdatabase.com and Google but nothing comes up. Any help identifying it is appreciated. Thanks!
