Prefer a wristwatch meself.
Got a fancy swatch off the mrs, looks great in the Frog and Parrot Friday nights, but competely naff for navigating.
Bought a very unstylish, extremely practical analogue wrist watch from argos, £4.99.
Has a white face, real numbers, graduated in minutes, black hands. Loses less than 30s each month. Fantastically simple, for when my mind blanks in the cockpit.
