Fancy watches. Fancy fancy automatic watches.
Breitling, IWC, TAG, Omega, Jaeger LeCoultre, Audemars Piguet, etc... but not Bell & Ross.
Silly aircraft cockpit instrumentation looking things they are.... to each their own I guess.
Also acceptable the decent Chinese autos like Sea-Gull or Perpetual or even BJWAF.
Cat food works too.
