Query: Reliable tool for officials

As a golf rules official, I need atomic time and to also have a stop watch. This watch fits the bill at a reasonable price. The readout is easy to see in all lighting and the functions are easy to use. It updates about 80% of the time overnight without placing it anyplace special. It is easy to know if it has updated and easy to do a manual update if the update did not happen automatically. The velcro strap fits all size hands. It is also easy to get to the calendar function when you need to know the date.
