The Marine 5527 in titanium is the lightweight sports-chronograph variant of the Marine family. Titanium cases require different finishing techniques than steel and the material should be verifiable by weight and surface response. The chronograph function and the presto-style bezel inherited from the Type XX family are the functional authentication points.

Titanium case
Original: Grade 5 titanium (Ti-6Al-4V). Titanium is roughly 40% lighter than steel for the same volume. The satin-finished surfaces have a slightly coarser texture than comparable steel-brushed surfaces. Titanium does not show the magnetic attraction that steel exhibits.
Replacement tells
Case weight heavier than expected for the case size -- a steel case of the same dimensions weighs significantly more
Magnetic attraction to a strong magnet (steel shows clear attraction; genuine titanium shows none or only very weak attraction)
Surface texture that reads as identical to steel under magnification -- titanium satin finishing has a slightly different grain character
Flyback chronograph mechanism
Original: Same flyback standard as the Type XX: instantaneous reset and restart on a single pusher press while the chronograph is running.
Replacement tells
Chronograph that requires stop before reset -- indicates flyback disabled or incorrect column wheel
Sluggish seconds hand reset taking more than one second
Case back markings

All production
"BREGUET" and serial number on exhibition caseback rim
Cal. 582Q or 583 engraved on movement plate
"TITANIUM" or "Ti" material designation on caseback or case flank
Reference 5527TI and variant code on caseback
Water resistance rating engraved on caseback
Movement tells

Titanium case should not be refinished by non-Breguet technicians -- titanium finishing requires different abrasives than steel and incorrect refinishing produces a visually distinct surface
Flyback function verification: same test as Type XX -- run the chronograph and press the flyback pusher for immediate reset
