“

The Unimatic Modello Quattro U4S-T-LB Limited Edition Time Only is a lightweight titanium field watch celebrated for its summery teal-green and gray California dial with mint-green lume, strong daylight legibility, and noticeably slim profile — reviewers praise the reasonable price and wearability at just 65 grams, a material and finish choice that distinguishes it from Unimatic's typically more affordable stainless steel line. The mint-green lume reads poorly in darkness relative to its daytime contrast, and the 22mm strap adds perceived bulk despite the case's minimal weight. Overall, reviewers rate the Modello Quattro U4S-T-LB highly for its lightweight titanium construction and summery aesthetic at a competitive $1,660 price point.
