Reviews

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Loresum Founder Edition

The Loresum Founder Edition is praised for its smaller 39.5mm case size and its Kickstarter price of around $600, which is significantly less than comparable watches. One owner purchased the Loresum LS04 "Founder's Edition Lunar Veil" because his wife liked its "nubbly quality." The movement is seen as a downside compared to a Sellita. Overall, owners rate the Loresum Founder Edition highly for its value at the price point.

Selten M1 Moonphase

Owners praise the Selten M1 Moonphase for its attractive aventurine dial, excellent finishing relative to its price point, and comfortable 39mm case size, noting a custom rotor on the Miyota 9015 movement. One commenter found the date window to look cheap. Overall, owners appreciate the Selten M1 Moonphase for its striking dial and value proposition.

From video reviewers

The guilloché dial—detailed and color-shifting across angles—commands attention and justifies extended wear. The bracelet rattles noticeably and the lugs feel sharp against skin.
