At 52 mm across and 13 mm thick, this is a deliberately oversized piece. The black ion-plated stainless steel case carries a deep blue dial arranged around three chronograph sub-dials — tracking seconds, minutes, and hours elapsed — alongside a date aperture at three o'clock and a secondary rotating disc for a second time zone. Luminous hands and hour markers remain readable in low light. The 24 mm black leather strap fastens with a steel tang buckle, keeping the fit straightforward despite the substantial case.

Learn more about Diesel
Renzo Rosso founded Diesel in Molvena in 1978, building a denim brand on deliberate irreverence. The watches, produced under licence by Fossil Group, carry that attitude directly.
Where most fashion watches aim for restraint, Diesel does the opposite: oversized cases frequently past 50mm, blacked-out finishes, exposed screws, multiple crowns, and dials that prioritise visual impact over legibility. The Mr Daddy models stack four time zones onto a single dial.
Whether that appeals is a matter of taste, but the design intent is consistent and unmistakable, which is more than can be said for much of the category.

Frequently asked questions, and things you should know about this watch
Can I swim with it?
No. At 30m it will survive rain and handwashing, but not submersion of any kind.
Water resistance explainedWill the glass scratch?
It can, over time. Mineral glass handles daily wear but will pick up fine scratches that sapphire would not.
Sapphire, mineral and acrylic comparedDoes it need a battery?
Yes. It is quartz, so expect a battery change every two to three years at a jeweller.
Quartz, automatic and solar comparedWhat size strap does it take?
24mm. Any strap of that width will fit, and on most modern watches quick-release bars make the swap a two-minute job with no tools.
Is it a men's or women's watch?
Listed as men's.
