Five requirements. Titanium case, solar-powered, alarm function, sleep tracking, and classic analog form with real hands. Not a single watch on the market today meets all five. Here is every contender worth knowing about, ranked by how close they get.
Four out of five. Titanium, sleep tracking, smart alarm, real analog hands, Swiss-made. The only miss is solar: 7-day USB charging instead. Discontinued but findable as new-old-stock on Chrono24 for $550-900. Grab it before inventory dries up.
Wear the titanium solar watch you actually love during the day. Let the Oura Ring Gen 4 handle sleep tracking from your finger. The ring is titanium itself, weighs 3 grams, and is the gold standard for sleep data. No wrist conflict, no compromise on the watch.
Alpina has both the AlpinerX Alive platform (titanium + sleep + analog) and the Solarmetre solar movement. Citizen has Eco-Drive solar, Super Titanium, and CZ Smart health sensors across three separate product lines. The building blocks exist. Nobody has assembled them yet.
