Is the Casablanca Theorema a good watch for daily wear?

It can be, but the 44mm case and 5 ATM rating make it better suited to office and dress wear than rough use. The sapphire crystal helps it hold up to daily knocks.

Does it need a battery?

No. It runs on a 17-jewel mechanical movement, so you wind it by hand and it has no battery to replace.

No. Its 5 ATM rating covers splashes and brief hand washing, not swimming or showering.

What is included in the box?

The original Theorema box, a manual, the warranty card and a future gift card.

How does it compare with other skeleton watches?

It offers sapphire crystal, gold IP plating and a two-year warranty at a level where many rivals use mineral glass. The trade-off is the large case and basic buckle.

Is the strap replaceable?

It comes on a stainless steel band with a standard buckle. A jeweler can swap it for another strap of matching lug width.
