I like small watches that do not apply and so rather inconspicuous do their duty. The Promaster meets all these demands. Small and easy to carry. Do me a Natostrap anxious to do so. is still a convenient eating. Super workmanship. Since there are no scratches. The glass is well protected by the slightly protruding bezel. The clock is very accurate so far. The first dive they survived with flying colors. The main purchase decision was ECO DRIVE! Never go back battery. When a Diver-clock always very expensive and annoying! I would buy this clock again.
