Description: This ladies’ Rado model is quite similar to one of the original series of Manhattan models issued by Rado in the mid-1960s and produced until 1973. Introduced a tad later (1970) and produced until 1974, this version is nearly identical to the men’s version except that the latter indicates the day & date while this model shows date only. Just as the larger model does, this example has the deep recessed case back which holds the movement in place, snaps to the bezel, and is protected by a large plastic crystal. The crystal, which has the Rado anchor symbol visible at its center, envelops the case back and is rendered water-tight by close contact with an o-ring gasket. Photos of this and more information on the men’s Rado Manhattan series can be found in this article.

The dimensions of this model are 24mm wide (square case, plus crown and lugs), 13mm thick (including domed acrylic crystal), 14mm between lugs. 

The two examples pictured feature the most frequently seen silver dial with wedge markers; it is unknown what other dial options were offered. A period bracelet is present on each—both are 'flat-clasp' 5-row ribbon types made by Novavit S.A.—one has the correct fitted end-pieces. This page from a 1972 Japanese catalog shows the men’s version of this watch and bracelet combination. A smaller "Mini Manhattan” model was also made which also resembles this watch.

The case front shows little wear and the back has some minor marks. The movement is keeping accurate time but has not been serviced nor examined; the date mechanism changes properly.
