An 80-hour reserve means you can take the watch off Friday evening and it will often still be running Monday morning.

Bracelet

These specifications make it a true recreational diving watch rather than merely a watch with a dive-inspired design.

Wearing Experience

Owners frequently praise:

• Strong value for money
• Long 80-hour power reserve
• Attractive silver dial that looks more refined than the typical black or blue dive watch
• Comfortable bracelet
• Versatility with both casual and business-casual clothing

Some collectors note that the 43 mm case can wear large on smaller wrists and that the Powermatic 80 movement is typically serviced through authorized service channels rather than by every independent watchmaker.
