Is the GUESS Blue Diamond watch worth it?

It is a fashion watch, so buy it for the look, not resale or horology. If you want a slim blue rectangular watch with diamond sparkle, it delivers that. Compare the live price against other GUESS and fashion watches before deciding.

How big does the 42 x 48 mm case wear?

That is a large case, closer to a men's or oversized unisex fit. The 9 mm thickness keeps it flat, but the 48 mm length can overhang a small wrist. Try it on or check the lug-to-lug fit if your wrist is under about 6.5 inches.

No. The 5-bar (50 m) rating covers splashes, rain and hand washing, not swimming or showering. Keep it away from hot water and don't press the crown underwater.

What movement does it use and does it need winding?

It uses a quartz movement, so it runs on a battery and never needs winding. Expect a battery change every couple of years.

What is the strap size and can I swap it?

The strap is 21 cm long and 21 mm wide, so a 21 mm replacement strap will fit. The foldover clasp with safety is part of the strap, so a new strap may need its own clasp.

When is the best time to buy it?

Our take on the GUESS Blue Diamond Rectangular Watch

The GUESS Blue Diamond is a quartz fashion watch with a tonneau (rectangular) case measuring 42 x 48 mm and just 9 mm thick. The blue case and blue dial are set with diamond accents, and it runs on a standard quartz movement with 5-bar water resistance. It is a statement piece rather than a tool watch, sized large on the wrist at 84 g. No current price was provided, so check the live comparison for today's best store price.
