The TAG Heuer Monaco CW2111-0 is a stainless steel automatic chronograph that belongs to the third generation of the Monaco collection, produced between roughly 1999 and 2009. It is often referred to as a "modern classic" because it moved the Monaco from being a limited heritage experiment into a permanent pillar of the brand's catalog, notably being one of the first models to feature the "TAG Heuer" logo on the dial instead of just the vintage "Heuer" logo. 

• Case Size: 38mm x 38mm square stainless steel case with a thickness of approximately 12.5mm to 12.8mm.
• Movement: Powered by the TAG Heuer Calibre 17 (based on the reliable ETA 2894-2), featuring 37 jewels and a power reserve of approximately 42 hours.
• Crystal: Traditionally fitted with a Plexiglass (acrylic) crystal, though some later listings or modified examples may mention sapphire.
• Water Resistance: Rated to 30 meters (3 ATM), suitable for light splashes but not for swimming.
• Dial Design: Deep black dial with three sub-registers: 30-minute counter (9 o'clock), 12-hour counter (6 o'clock), and small seconds (3 o'clock). The date window is positioned at 6 o'clock.
