During the industrial revolution, the invention of steam locomotives brought transportation to another level. The black, gray and copper colors found in a locomotive cockpit inspired the colors of the Q2/03. The decentralized disc redesigned to 12-hour disc with AM/PM indicator give a glimpse into the earner working of these iron beasts. The moving minute hand and timer recall the manometers that measure pressure with every move of the locomotive. The railroad track leather strap is wax-treated and gives a worn leather feel with each wear. Please Note: Leather is a natural material. All straps vary slightly and each will develop a vintage patina from wear adding to their character. Most scratches and scuffs can be wiped away with a slightly moist cloth.
