Hello, just share some pictures from a LMC (Leon Military Chronograph) watch in a case and movement of a 80th Heuer(-Leonidas) 2000 series from Heuer. It has the LWO 283 movement. You can see on two pictures the back - inside labeled as Heuer-Leonidas SA and the LWO 283 movement. Overall in nearly mint condition with new leather strap.Like the color of the dial and counters really. Cheers.
