I too like a pocket watch better than a wristwatch it looks stylish and for me the larger face is a must.
I have found that it is a simple matter to sew a pocket inside the apron of my kilt to hold the watch and run a chain with a clip type end under my belt and clipped to my kilt to secure it. Q.E.D.! When I wear a waistcoat it then of course resides within the pockets there.
