Up for sale is a rare and collectible vintage Casio Marlin H101 men’s digital sports watch from the 1980s, powered by Module 106. This Japan Domestic Market (JDM) release is part of Casio’s iconic Marlin series, known for its rugged construction, bold design, and 100M water resistance, making it a standout example of classic 1980s digital sports styling.

The watch is in full working condition, and all confirmed features and functions operate properly, including timekeeping, alarm, chronograph, and display functions.

The watch is fitted on an aftermarket stainless steel strap. The case and module are original. The watch shows heavy signs of use and age consistent with decades of wear. Please review all photos carefully, as they best describe the physical condition.

There is a mark visible in the top right corner of the crystal/dial area. This is not a chip in the glass, but appears to be some sort of bubble or internal mark that has formed beneath the crystal.
