PILOT WRISTWATCH BLACK FACE 1950`S MECHANICAL

THIS IS A PILOT WATCH WITH BLACK FACE TWO SETS OF NUMBERS, THE OUTSIDE FOR MINUTES COUNTING AND THE INSIDE FOR HOUR COUNTING, IT HAS ARROW AT TWELVE O`CLOCK. THE SECONDS HAND IS RED COLOUR, IT IS A HAND WINDING IN WORKING ORDER, I THINK IS A SCREW BACK . ON THE BACK IT SAYS:(STAINLESS STEEL BACK, SHOCK RESIST, DUSTPROTECTED. NO NAME FOR THE WATCH BUT I THINK THE NAME IS INSIDE BUT I AM NOT ATTEMPTING TO OPEN IT. IT HAS BLACK STRAP IT SAYS ON IT :(18 CALF GRAIN). SOME MINOR SCRACHES ON THE GLASS NOT VISIBLE. GOOD LUCK THERE IS A NUMBER ON THE BACK 2209
