Invicta Speedway Chronograph 9211 vs Invicta Automatic Pro Diver 8926

Buy the Speedway 9211 if you want a quartz chronograph with a tachymeter, subdials and a date, and you like a white dial that works with a suit or a polo. Buy the Pro Diver 8926 if you want a mechanical watch: its 21-jewel Japanese automatic movement has a sweeping second hand and a see-through case back, and it needs no battery. Both are stainless steel, 200 m water resistant and use mineral crystal, so the real split is quartz chronograph versus automatic diver. Owners of the 8926 line praise its Seiko-style NH35A movement and solid feel for the money; the Speedway's 13 ratings at 4.6 suggest buyers are satisfied, but the sample is small.

• Choose the Invicta Speedway 9211 if you want chronograph functions, a tachymeter and a white dial in a lighter 39 mm case.
• Choose the Invicta Pro Diver 8926 if you prefer a self-winding automatic movement, a black diver dial and a see-through case back.
