The Unimatic Modello Quattro U4S-T-LB Limited Edition Time Only is a lightweight titanium field watch with a colorful California dial and mint-green lume, offering a slimmer profile than its stainless steel predecessors. Reviewers praise its reasonable price and summery aesthetic, noting the teal-green and gray color scheme excels in daylight with strong legibility and aesthetic contrast. The sandblasted titanium case weighs just 65 grams and wears noticeably lighter than steel alternatives, though the 22mm strap adds perceived bulk. The Sellita SW200-1 automatic movement and 300m water resistance distinguish it from Unimatic's typically more affordable models, priced at $1,660 for 300 pieces. On balance, reviewers rate the Unimatic Modello Quattro U4S-T-LB Limited Edition Time Only highly for its lightweight titanium construction and summery aesthetic at its price point.
