The TAG Heuer Aquaracer Professional 300 Green 42mm (Ref. WBP5116.BA0013) delivers professional diving capability through COSC-certified in-house Calibre TH31-00 with 300m water resistance, combining the deep green wavy pattern dial and vivid lime green seconds hand with green ceramic unidirectional 60-minute scale bezel for cohesive maritime character. The Super-LumiNova filled hands and indexes ensure ultra-legible time reading in low-visibility underwater conditions essential for professional diving applications.

At 42mm with 12mm thickness through fine-brushed and polished stainless steel construction, this provides substantial diving watch presence in a notably slim profile for a 300m diver, ensuring comfortable daily wear beyond aquatic use. The green ceramic unidirectional bezel provides superior scratch resistance whilst the screw-down crown maintains water resistance integrity throughout demanding diving applications.

The in-house Calibre TH31-00 delivers an exceptional 80-hour power reserve through automatic construction operating at 28,800 vibrations per hour with COSC chronometer certification confirming precision standards. The comprehensive hours, minutes, seconds, and date functionality provides complete practical daily instrument capability.

The fine-brushed and polished three-row steel bracelet with folding clasp and double safety push buttons ensures secure attachment during active aquatic use whilst maintaining refined daily wear aesthetics. The 300m water resistance and ceramic bezel combination position the Aquaracer Professional 300 firmly within serious diving watch territory.
