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.

The case of the PT6108-TT031-391 measures approximately 45mm wide (not including the crown) by 14mm thick and is water resistant to 50 meters. This should be sufficient for splashes, rain, baths & showers but is not recommended for swimming or diving. The watch has a display back to show of the ML121 movement.The titanium bezel is fixed (cannot be rotated). The gap between the lugs is 22mm and the leather band can be removed using a band removal tool to be replaced with another band.

  • Second hand
  • Minute hand
  • Hour hand
  • GMT hand to show the hour in another timezone
  • Date window to show the day of the month. Note that some watches may be damaged if you attempt to change the date between 8:00 PM and 2:00 AM, in which case you should change the time to be outside that range first then reset the time after adjusting the date. Check your watch manual for details.
  • Moonphase window to show the phase of the moon
