Bulova vs Longines: Which Is Better?
Longines is two bands up and earns most of it: the HydroConquest Automatic runs the L888.5 with a silicon balance spring, 25,200 vph and a 72-hour reserve, rated 300m with a ceramic bezel, in the $1,500–$2,500 band. The Bulova Devil Diver Oceanographer runs a Miyota 8215 with a 42-hour reserve, rated 200m with sapphire, in the $500–$1,000 band. Buy Longines for the movement, the reserve and the extra 100m; buy Bulova for a sapphire 200m automatic diver at a fraction of the price.

Movements: silicon-sprung Longines vs Miyota Bulova
The Longines HydroConquest Automatic runs the L888.5, an ETA-based automatic with a silicon balance spring at 25,200 vph (3.5 Hz), 21 jewels and a 72-hour reserve. The Longines Master Collection Moonphase runs the L899 (ETA A31.L91 base), also 72 hours, with moonphase and pointer date.
Bulova's Devil Diver Oceanographer and Surveyor Automatic both run the Miyota 8215 at 21,600 vph (3 Hz), 21 jewels, 42-hour reserve. The Longines reserve is 30 hours longer, and the silicon balance spring is a feature Bulova does not offer in our catalogue.
Build and water resistance
The HydroConquest is 41mm steel with AR sapphire, a unidirectional ceramic bezel and 300m (30 ATM). The Devil Diver is 41mm steel with sapphire and 200m (20 ATM). The Bulova Surveyor is a 39mm dress automatic with sapphire and 30m (3 ATM); the Longines Master Moonphase is a 40mm dress watch with sapphire and 30m.
Same case size on the divers, 100m difference in rating, and a ceramic bezel on the Longines.
Price positioning
The Bulova models in this comparison land in $250–$500 (Surveyor, Classic Automatic) and $500–$1,000 (Devil Diver). Longines lands in $1,500–$2,500 (HydroConquest) and $2,500–$5,000 (Master Collection Moonphase). There is no shared band, so the question is whether a 72-hour silicon-sprung Swiss movement, 300m and a ceramic bezel are worth two bands over a 42-hour Miyota with sapphire and 200m. For a first automatic diver, Bulova; for the long-term watch, Longines.
