Choose the Casio Duro MDV-106 if…
- You want set-and-forget timekeeping: quartz holds to seconds a month and the battery lasts about three years.
- You prefer a larger watch: a 44 mm case on a resin strap that fits any wrist size without resizing.
- Price decides it: today the Duro is $67.88 against $91.25 for the Invicta.
Choose the Invicta Pro Diver Automatic if…
- You want a mechanical movement: the NH35 hacks, hand-winds and sweeps; expect roughly ±20 seconds a day rather than a month.
- You want a steel bracelet and a 40 mm case in the classic Submariner-style proportions.
- You plan to swap straps: 20 mm lugs take the widest range of aftermarket bands.
