Well, it’s grand (i.e. “big”), and it’s a #Seiko, so I thought… Why not?! If you want to time things to the nearest 1/100th of a second mechanically, you don’t need to spend over $50k on an #FPJourne #Centigraphe. Seiko were solving that problem back in the 1960’s. This particular stopwatch – model number 8941-5000T – hails from April 1963. Developed for use in the 1964 #Tokyo #Olympics, the watch can time events up to 10 minutes in duration. The small central hand marks off the minutes, whilst the small hand above it counts the seconds. The large hand makes one full revolution every 3 seconds, and with the watch tick-tocking away at 360,000 bph (no, that is not a typo!), it can measure time down to 1/100th of a second. The front of the case removed so that I could get a clear view of the dial (how I wish all watches could do this!), and in the background, the Japanese Seiko newsletter from June 1964.
