Hello,
I'm a new member to the forum and have just bought my first love, a 35.205.300 MK40 Schumacher.
I started adoring this watch at the end of the 90's and in those days spent much of my spare time with my nose pressed against watch shop windows.

I'm assuming that it's from the late 90's since it has the defined minute markers,but the year on the warranty card is blurred but appears to be year 00, the serial number is 56562746 and I was hoping that someone on the forum could help in identifying the year of manufacture.

 

Well it’s later than 1997 since that was when the SL dial was introduced which yours has. They were also available with a short time with the earlier tritium dial. The serial sounds low for a year 2000 watch so my educated guess is circa 1998. It could of course have been sold several years after manufacture.
