“Purchased to wear on the motorcycles, road/trail and engine vibration can distroy all but the best ISO rated dive watches. Because my dive watches tend to be bulky under a jacket sleeve and glove cuff, I’ve decide to try this well built slim and light weight alternative. Why only 4 stars ? I can’t for the life of me understand why a $15 quartz Timex can have a second hand that lands on each and every second mark of the dial but Marathon can’t seem to do it on a $300 Watch.”
