Maurice Lacroix PT6108-TT031-391 Moon Phase Watch

PT6108-TT031-391

Overview

The Maurice Lacroix Pontos Decentrique GMT PT6108-TT031-391 is a 45mm men's automatic watch with a titanium case and a black-silver analog dial protected by sapphire crystal. It uses a ML121 caliber self-winding mechanical movement that can be manually wound and hacked (the second hand stops when the crown is pulled out). It ticks 8 times per second which gives the second hand a smoother movement than quartz watches which tick once per second. The watch should run for up to 40 hours when fully wound and will self-wind when moved.

The PT6108-TT031-391 is currently ranked #91 in popularity out of 345 watches in this catalog. Check availability on Amazon.com.
