Bulova vs Casio: Which Is Better?
Bulova and Casio mostly answer different budgets: Bulova's watches in our catalogue — Miyota-powered automatics and the 262 kHz high-frequency quartz Lunar Pilot — span the $250–$500 and $500–$1,000 bands, while Casio's span Under $50 to $100–$150, topped by the 200m Duro diver in the $50–$100 band. Pick Bulova for mechanical movements and sapphire at mid-tier money; pick Casio for unbeatable function per dollar.

What Bulova brings
Bulova's Devil Diver Oceanographer 96B350 is the headline spec: a Miyota 8215 automatic (21 jewels, 42-hour reserve), sapphire crystal, and a genuine 200m rating in the $500–$1,000 band. The Surveyor Automatic brings the same Miyota movement down to the $250–$500 band with a mineral crystal and 30m rating.
The Lunar Pilot Chronograph is Bulova's most distinctive engineering: a high-performance quartz movement running at 262,144 Hz — eight times the frequency of standard quartz — driving a chronograph with tachymeter under sapphire, in the $500–$1,000 band.
What Casio brings
Casio dominates the tiers below. The F-91W digital sits under $50 with a 7-year battery; the AE1200 World Time adds 48-city world time, five alarms, and a 10-year battery, also under $50; the solar MTP-S120L ($100–$150 band) recharges from light and never needs a battery swap; and the Duro MDV106 is a full 200m screw-down-crown diver in the $50–$100 band.
Nothing in Casio's lineup here is mechanical, and nothing uses sapphire — that is the trade for prices this low.
The decision
If your budget is under about the $150 mark, Casio is effectively unopposed in our catalogue. From the $250–$500 band upward, Bulova starts offering things Casio does not: automatic movements, sapphire crystals, and the 262 kHz chronograph. The closest direct fight is dive watches — Bulova's Devil Diver (automatic, sapphire, 200m) against Casio's Duro (quartz, mineral, 200m) several price bands apart.

Frequently Asked Questions
Is Bulova or Casio better?
They serve different budgets. Casio owns the tiers from Under $50 to $100–$150 with quartz, digital, and solar watches — including the 200m Duro diver. Bulova's automatics and its 262 kHz quartz Lunar Pilot run $250–$1,000 and add sapphire crystals and mechanical movements Casio doesn't offer at its price points.
What is special about Bulova's 262 kHz quartz movement?
Standard quartz oscillates at 32,768 Hz. The Bulova Lunar Pilot's high-performance quartz movement runs at 262,144 Hz — eight times faster — which is its defining technical feature.
Which Casio is closest to a Bulova dive watch?
The Casio Duro MDV106: like the Bulova Devil Diver 96B350 it is rated 200m with a unidirectional bezel and date. The Bulova adds an automatic Miyota 8215 movement and sapphire crystal; the Duro is quartz with mineral glass at a fraction of the band.
