Reviews

Certina DS-7 Powermatic 80

Owners widely praise the Certina DS-7 Powermatic 80 for its excellent finishing and value, with many highlighting its versatility as a dress watch that looks good on bracelet or strap. Reviewers and owners note its comfortable wearability, with some appreciating its thinness for an automatic and others finding the 39mm case size wears well, though a few suggest it can wear larger than its dimensions due to the chapter ring.

On balance, owners and reviewers rate the Certina DS-7 Powermatic 80 highly for its finishing and value proposition.

Hamilton Jazzmaster Day Date Auto

Owners widely praise the Hamilton Jazzmaster Day Date Auto for its versatility as an everyday and business-casual timepiece, with some questioning its suitability for formal wear. One owner selected it as an engagement gift, viewing it as a strong foundation for a watch collection, while another found it to be the best-fitting option after trying several watches. The Hamilton Jazzmaster Day Date Auto is also noted for offering great value for money. Overall, owners rate the Hamilton Jazzmaster Day Date Auto highly for its versatility and perceived value.

From video reviewers

The watch offers excellent build quality for its price point, with an 80-hour power reserve from the H-40 movement. The 50-meter water resistance is a limitation. Reviewers disagreed on the aesthetic appeal of the date window at 6 o'clock.
