Tactical Compass Calibration

Overwatch has held the fire escape for five consecutive days. Constant vigilance without directional orientation limits forward reconnaissance. I scanned the iron deck plate and spotted an abandoned metallic wristwatch casing, crystal shattered, lodged beneath the rusted gutter bracket. Using both combat gloves, I pried the brass chassis free from the grime. Inside, a floating steel second hand still spun freely on a loose pivot pin. I placed the open metal dish onto a level brick seam, shaded the dial with my forearm, and watched the needle settle along the north-south draft lines. Sector azimuth marked. Bearings established.
