The continued popularity of the Spaceview has unfortunately resulted in many standard 214-based Accutron watches having their dials removed. In the past, it was a simple matter to identify a Spaceview conversion, as most factory models were equipped with white hands, while non-Spaceview models were typically equipped with gold or silver hands. This is no longer the case, as there is now a healthy aftermarket for high quality replica Spaceview parts, including white hands, printed crystals and dial spacers. An educated estimate suggests that at least 90% of extant Spaceview watches are aftermarket conversions.


Typical 214 Spaceview conversion, built from a US-made M9 (1969) 14KGF case, Swiss-made M6 (1966) 214HN Astronaut movement with hack spring and GMT components removed, replica white hands, dial spacer and replica printed crystal. Though the watch has the correct overall appearance of a factory Spaceview, this specific case style (#2500) was never offered in a Spaceview variant.

Although the full process of Spaceview authentication involves an examination of a number of key features, the majority of conversions can be easily identified by checking the case number. Accutron case numbers are located on the inside of the case back, either stamped in black ink or engraved directly into the metal. The table below lists all known Spaceview case numbers, as well as associated crystal and reflector part numbers when available. Take note that case numbers can be altered, and all 214 case backs are fully interchangeable.
