Here is my spectacular Breguet Type XXII high frequency 10Hz stainless steel chronograph on bracelet, reference 3880st/h2/sx0. This is a very technically interesting watch to me; its in-house caliber 589F movement vibrates at 10 Hz, or 72,000 vibrations per second. This enables the watch to measure down to 1/10th of a second, a cool bragging factor among the WIS circle. The showmanship goes farther with both the running and chronograph second hands completing an entire 360 degree revolution in 30 seconds, a noticeable 2x speed from standard watches. Furthermore, the watch comes with Breguet's signature central-mounted chronograph minute counter, a 24 hour indicator, and a second timezone indicator at 6. Finally, a partial display case back highlighting the quick balance wheel completes this technology powerhouse. A video demonstration of the watch may be seen here: The watch is in 92%+ condition. A few small desk diving scratches do exist, but they're very minor and can be cleaned up at the next service, if desired. It is a good, honest, and solid watch. The watch comes complete with the boxes, papers, and additional OEM bracelet links, as pictured. It even includes the original AD purchase receipt. Asking $8,895 shipped CONUS. Please add $65 for international. Or trade for?
