Original Casiotron R 15 1975 Retro Vintage 70s

Manufactured in 1975 Original Casiotron R-15 This is the original watch that serves as the prototype for the TRN-50, recently produced by Casio as a 50th anniversary limited edition. Unlike modern watches, it reflects the aerodynamic design of that era. Furthermore, because it features a full stainless steel case rather than a resin one, it offers a delightful weightiness when worn. The exterior and internal components, as well as all functions, are perfectly preserved. A very rare piece that embodies both the history and value of Casio. (Photo attached after wearing it once; currently kept as part of my collection) - Full stainless steel case (no signs of use) - All functions working normally (time, calendar, day display) - Battery replaced - Time and date set correctly Product Condition: Almost brand new
