Measuring 39mm x 45mm x 13.5mm the solar chronographs are sized like their ‘60s forefathers, making for comfortable all-day watches. The solid steel cases feature a compact barrel design with brushed and polished surfaces. Surrounding the sapphire crystal is a large external tachymeter with a beveled edge for a cool, three-dimensional look. The triple-register dial is pure ‘60s with applied markers on a textured surface. Sunlight is cleverly collected through the sub-dials to power the watches.
Inside of the Prospex Speedtimer Solar Chronograph is the Caliber V192. Powered by light, this movement features a ⅕ second sweeping chronograph hand, 60-minute counter, 24-hour hand, power level indicator, as well a power reserve of 6 months.
Looked at the watch and it looks like it's not running slow but the second hand gets stuck. As soon as I move it starts running again. Why ideas on what would cause the second hand to intermittently get stuck?
