The Jobclock is a durable modern punch clock, designed especially for the rugged and demanding environment of the construction and contracting trades. This design has improved durability and functionality to endure its environment. The body is designed out of recyclable materials that contribute to the long product life – stainless steel and aluminum, with an injection molded polypropylene guard that resists abrasion, an acrylic lens, and an internal chassis that withstands dropping. Mechanical seals, O-rings, revised venting, and a Gortex membrane surrounding the audio vent improve water resistance. Simpler assembly helps to accommodate battery maintenance at various job sites, while a larger circuit board offers functional improvements. The user experience reflects the rugged environment in which the product is used.
