    Watch holder alternative
    From: David Pike

    British aircraft sextants from at least the ubiquitous MK 9 onwards didn’t need a watch holder.  The navigator wore his watch on his left wrist pointing inwards.  In the right-hand handle was a 3v pea bulb to light up the counters.  A piece of Perspex strip was fed down the inside if the handle and pointed out at the bottom towards the left.  As you know, light does funny things in Perspex.  Every time the navigator twisted the lever or pushed the button to light up the counters on the right hand side of the sextant, a beam of light also shot out to light up his left wrist.  Cunning eh!  It’s possible to look through the eyepiece with one eye and at your watch with the other.  A similar thing is possible with the light on a Hughes marine sextant if you wear your watch on the inside of your right wrist, but not whilst you’re looking through the sextant, and you’d probably ruin your  night vision.
