Vintage Casio TGW-10 Tri Graph Digital Watch Module 827 Japan 100M 38.5mm Box

About this watch

The Casio Tri Graph TGW-10 is one of Casio's most distinctive late-1980s digital designs: three round graphic LCD windows sit above the main display, showing the time as animated analog-style hands (TIME), an AM/PM target graphic in the centre, and a sweeping radial seconds graph (SEC). Below them a large positive LCD shows hours, minutes and seconds, with a second line for dual time, alarm, timer and stopwatch. This example is housed in a black resin case with four steel pushers and a screw-down stainless steel caseback stamped "CASIO 827 TGW-10, Stainless Steel Back, Water Resistant, Japan".

Brand heritage

Casio entered the watch market in 1974 with the Casiotron and became one of the defining names in digital watches. In the 1980s Casio experimented boldly with graphic LCD displays, and the Tri Graph (module 827) is a sought-after example from that era, sharing its rounded sport case style with the Digi Graph DGW-30.
