The TAG Heuer 1500 Professional GMT (Reference 155.706) is a Rare and highly collectible, "Jumbo" sized vintage timepiece from the mid-1990s. It stands out as one of the rarest and most unique iterations within the utilitarian 1500 Series, which bridged the gap between the older 1000 Series and the refined 2000 Series.

• Case Size: 40mm diameter (excluding the crown), often referred to as the "Jumbo" size for this era.

• Movement: Precise Swiss Quartz movement (typically built on the reliable ETA 255.266 base caliber). 

• Aesthetics: A striking bicolor (two-tone) stainless steel and gold-plated finish on the case, bezel, and bracelet. 

• Dial: Crisp white dial accented by tritium or early Super-LumiNova plot markers and classic Mercedes-style hands. 

• Bezel: Highly functional bi-directional rotating bezel engraved with 24-hour markings to track a second time zone alongside the red-accented GMT hand.

• Water Resistance: Rated for 200 meters (20 ATM), equipped with a screw-down crown and a case back typical of TAG Heuer’s classic professional dive features.
