The design of the Tribune Limited Edition Valjoux 7753 series chronograph shows a balance between color patterns and forms. The Arabic numerals finished in blued steel on the silver guilloche dial provide a balanced contrast against the watch's stainless steel case and bracelet. Color accents on each of the chronograph's three recessed sub-dials further enhance readability. The case and bracelet are produced from surgical grade stainless steel (316L) with alternating brushed and mirror finishes. The 40mm-diameter case is water resistant to 100 meters/330 feet, and houses a superior-quality Swiss-made, rare automatic Valjoux 7753 chronograph movement. The case is topped with double-curved, scratch-proof sapphire crystal glass that gives a clear three-dimensional view of the dial. On the backside of the case, you can observe the watch's movement through clear sapphire-crystal glass.
