My order number is T18664. The watch does not keep time and the manual winder is very hard to wind.  The time looses as much as 1 to 2 hours a day when I wear it.  I keep all my automatic watches in winder boxes and this watch is the only one that does not keep time. This is 1 of 6 Tufina Watches I own.  I have a Silver White Version of the Marco Polo as well and it works just fine with no issues.  Please repair or replace accordingly. Thank you for your help.
