Stepping up in the same colour and case shape
The Mega Chief is built around a 51mm round case in black PVD-finished stainless steel, sitting 12mm thick on the wrist. A fixed black ion-plated bezel frames the black dial, which carries chronograph subdials, a date function, and luminous hands and markers for low-light legibility. Mineral crystal covers the dial. The black stainless steel bracelet fastens with a push-button deployant clasp and, at 202g total, the watch carries genuine weight on the wrist. Lug width is 26mm, and water resistance runs to 100 metres.

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?
Yes. At 100m it is rated for swimming and snorkelling, though not for diving.
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 comparedIs it a men's or women's watch?
Listed as men's.
