At WatchesToBuy.com we always try to purchase rare and interesting watches that many collectors have not seen prior! Here is another great example. The chrome plated case with signed, stainless steel screw back measures 34.5mm and with the naked eye, looks fantastic…without major scratches or dings. This dials on these watches are very interesting. The apertures at each marker display “green” during the day, then after 12:00 am. they turn black. The manual winding GRUEN movement was just cleaned and keeping time perfectly.
