Excellent reproduction and a solid watch.
Excellent reproduction of the original prototype. Size and markings are near perfect. Functionality, is vastly improved with the quartz movement. The main fault of these watches originally was the inacuraccy of the mechanical movement. With the quartz movement it's steady within a +/-1 second in month. This makes the original elapsed time function an actual tool. The dials on the side are easy to use with the watch on the wrist, which makes calculations a breeze! This is an honest and faithful update to a unique watch design that has been lost to history. It keeps true to the look and vintage feel while updating the technology where it counts. Wonderful watch please keep these in stock. Will buy again!
