Founded by Helmut Sinn in 1961, SINN is a brand that still exists today.
"I'm not making watches. I'm making a measuring instrument. This is the word Helmut Sinn spoke.
As the word says, SINN watches are easy to see and do not break, which is exactly the essence of a pilot watch.
This watch uses tritium for luminous as the notation "T SWISS MADE T".
The Arabic numeral index and the luminous hands are very nice colors, aren't they?
103.B.AUTO.POL.TY is a discontinued model that was discontinued around 2013, but this model number is often seen in cursive on the counter at 6 o'clock ( German ) only written "Automatik".
Models without Automatik are 103.B.AUTO.POL.TY is the oldest model, so I think it's quite rare.
The case diameter is 40 mm, which is the ideal size for a chronograph. When I wore this watch around my 16.5mm arm, it was just the right size.
I matched brown punching leather, but NATO strap is recommended in the hot season.
Stainless steel case, screw-down crown, screw-in back cover and water resistant watch, so it's good to use all seasons.
