Devon Tread 1E Wristwatch

Partially verified

The Devon Tread 1E is an American-made wristwatch featuring a belt-driven time display mechanism that eliminates traditional hands. The watch utilizes four intersecting belts displaying hours, minutes, and seconds, with white numerals printed on black belts. The case is constructed from stainless steel with a black DLC coating, measuring 53.3 by 47 mm with a 19 mm thickness. A transparent cover reveals the internal mechanics, which are powered by an electromechanical movement driven by four miniature electric motors controlled by optical sensors. The device is powered by a rechargeable battery, which includes a power reserve display indicated on the second-hand belt when the main display is inactive. The timepiece is paired with a black rubber strap and a signed Devon buckle. This model is delivered with its original box, which integrates a wireless charging system for the battery.

Object description

Case and Display

The Devon Tread 1E features an industrial design defined by a large stainless steel case measuring 53.3 mm by 47 mm, finished in a black DLC coating. Its structural depth is 19 mm. The primary visual feature is the absence of traditional hands; instead, the watch employs a series of four intersecting belts that rotate to indicate time. White numerals on the black belts align within a clear housing, allowing for observation of the internal movement.

The case is fitted with a black rubber strap, which attaches to the case frame and closes with a branded buckle. The design emphasizes the visibility of the internal mechanics, and the overall aesthetic is categorized as industrial and modern in the documentation provided.

  • “ابعاد این قاب ۵۳.۳ در ۴۷ میلی‌متر با ضخامت ۱۹ میلی‌متر است”
  • “پوشش شفاف گسترده روی صفحه به بیننده اجازه می‌دهد تا پیچیدگی‌های مکانیکی داخل ساعت را به‌خوبی مشاهده کند”

Movement and Functionality

The watch operates on an electromechanical movement, powered by a rechargeable battery. The system utilizes four miniature electric motors to drive the time-telling belts, with optical sensors monitoring the position of each belt to ensure accuracy. This technology is patented.

An advanced feature includes a power reserve indicator. When the primary display is inactive, the belt designated for the seconds indication switches to display the remaining charge of the battery. The watch is designed to be charged using a wireless system incorporated into its original presentation box.
