What owners report

Owner posts and owner reports. Each covers one watch, so read them as things to check rather than a verdict.

Reliability1 report

  • The owner reported that a heavily used Alpha GMT movement still ran after fifteen years, but its crown tube had broken and its twelve-o-clock marker had detached.

    Owner post on watchuseek.com, 19 Jan 2019

Service and support1 report

  • The owner could not find a reasonably priced repair and instead bought a used replacement watch head while reusing the worn bracelet.

From owners1 report

  • Owner discussion distinguishes older RK4D/Shanghai B GMT movement from a more recent iteration and notes concerns about the older movement longevity.
