CONTAX REAL TIME WINDER SYSTEM with All Original Boxes ・Real Time Winder 　Purchased July 1977 ・IR (Infrared Red) Remote Controller Set 　Purchased February 1981 ・Interval Timer ・Instruction Manual This is a Real Time Winder (RTW) system released by Contax over 40 years ago. I believe that there are very few working units with their original boxes remaining. How about it as a collector's item? 【Condition】 ・Winder: I have confirmed that it works without any problems when connected to a Contax RTS. There is no battery leakage in the battery compartment. ・Infrared Controller Set: This is a set of a transmitter (remote control) and a receiver. There are no problems with its operation. The receiver can be attached to the camera body's accessory shoe and can be rotated 360°. (Reference: The remote control battery is 006P) ・Interval Timer: Because it is electric, it does not have the accuracy of a quartz clock. The timer only operates on the second markings. It cannot be used at intermediate markings. ・The original boxes have deteriorated and have scratches and stains due to aging. It is a beautiful item without any noticeable scratches or stains, but it is a personal item that has been stored for a long time. Please refrain from purchasing if you are nervous or seeking perfection. RTS RTSⅡ RTS Winder RTW System
