As mentioned in the previous article on the gold cap 5722-9010, it is not possible to differentiate between dial-side images of that earlier reference and the 5722-9011 that replaced it.

Whilst there is little doubt that the watch listed in the supplement to 1966’s number 1 catalogue would be the 5722-9010, we don’t know exactly when the -9011 was introduced, and the confusion of a non-existent variant being show in 1967’s number 2 catalogue does not help matters.

However, when it comes to distinguishing between the two gold cap references in the 57GS series, there are no such problems. Each reference is identified by its movement-case reference number on the caseback, and the medallion for the earlier -9010 is the lion one, whereas that on the -9011 is the GS logo medallion.

Whilst we have not examined sufficient examples of each of the references to be absolutely sure, we would expect that the 5722-9010 would have originally been fitted with the 5722A movement, and the 5722-9011 with the later 5722B movement.

However, as with the steel cased models, it is entirely possible that other combinations can be found.

Catalogues and other official Seiko publications

As mentioned above, the 5722-9010 debuted in the supplement to 1966’s “No. 1” catalogue, remaining in the range until its final appearance in 1968’s volume 2. Since the catalogues only include dial-side photos, it is not possible to distinguish between appearances of the 5722-9010 and the 5722-9011.

In addition to the above catalogues, the gold cap 57GS also has mentions in issues of the monthly Seiko Sales bulletin that was distributed to retailers.

December’s 1966 issue shows the watch priced below a photo of the 5722-9990 in steel. As mentioned above, the 5722-9010/1 does not exist in the configuration shown here.

November’s 1967 issue lists the cap gold watch under the correct photo of the steel 5722-9991.
