The Vulcain Aviator uses the same Cal. 120 Cricket alarm movement in a modern titanium aviation case with a rotating outer ring. Authentication follows the same dual-crown and alarm-function logic as the 50s Presidents Watch. The titanium case adds a specific weight verification point.
Known issues in the market
Alarm function must work correctly; same two-crown test as the 50s Presidents Watch applies.
Titanium case is noticeably lighter than a steel case of the same dimensions; a Vulcain Aviator that feels steel-weight is likely not titanium.
The outer rotating ring for elapsed-time tracking should turn smoothly with a positive click detent; a ring that is loose or spins freely without detent is a service issue or a substituted case.

What to check
What is correct
Red flag
crown
Two-position crown
Same two-position crown architecture as the 50s Presidents Watch; lower position for time movement, upper position for alarm; both engage cleanly
Single-position crown only; no distinct difference between winding and alarm positions
movement
Alarm function with distinctive buzz
Same 20-25 second buzzing alarm as the 50s Presidents Watch; sound carries through the titanium case; vibration felt on the wrist
No alarm function; click-only alarm; alarm that does not sustain for at least 15 seconds
case
Titanium case weight and texture
Titanium is roughly 45% lighter than stainless steel of the same dimensions; the case has a characteristic matte or lightly brushed titanium surface finish; no magnetic attraction to a magnet
Case weight consistent with steel rather than titanium; magnetic attraction to a magnet (titanium is non-magnetic); surface that looks polished to a mirror rather than titanium matte
case
Rotating outer ring with click detent
Outer ring rotates in one direction (unidirectional safety design for aviation) with a positive click detent at each minute position; ring is secure with no wobble
Ring that rotates in both directions; loose ring with no click detent; excessive play in the ring that could allow accidental rotation
Common legitimate replacements
Strap and bracelet replacements are common.
Expert resources: Vulcain authorized dealers can authenticate via serial number. The alarm function is the definitive test for any Cricket-movement Vulcain.
