Here's a very unique Vintage Woman's Steampunk Watch.  This watch features a unique 4-wire (small stranded cables) wrist strap that is endlessly adjustable for any size wrist (within reason).  The 4 multi-stranded cables run through the edge of the watch case and wrap around your wrist.  Two sliding bars at the two ends of the cables slide to adjust for your wrist size.  It's a little tricky doing this the first time one handed but you'll figure it out. A little help from a friend does the trick as well.
