Longines Hydroconquest GMT 43mm Blue Dial Watch L3.890.4.96.9

The Longines Hydroconquest GMT 43mm Blue Dial (Ref. L3.890.4.96.9) combines legitimate diving capability with proper GMT functionality for travellers who need both underwater performance and dual-time zones. The 300m water resistance places this in professional diving territory whilst the 24-hour GMT hand enables tracking of home time during international diving expeditions.

At 43mm with 12.90mm thickness, this provides substantial diving watch presence without excessive bulk. The blue dial and ceramic bezel create sophisticated appearance whilst maintaining the high contrast legibility essential for underwater timing. The unidirectional ceramic bezel offers genuine durability advantages over aluminium alternatives with superior scratch resistance and colour retention.

The exclusive Calibre L844 delivers 72-hour power reserve with silicon balance spring technology for enhanced magnetic resistance. The weekend-proof power reserve accommodates irregular wearing patterns during travel, whilst the silicon technology provides reliability in modern environments filled with electronic diving equipment and magnetic interference.

The GMT function operates independently, allowing quick time zone changes without stopping the watch or affecting the primary timekeeping. This proves genuinely useful for international diving professionals who need to coordinate with different time zones whilst maintaining accurate dive timing.

This Hydroconquest GMT suits buyers who need legitimate diving capability combined with travel functionality. Unlike dress GMT watches that compromise water resistance, or basic dive watches without dual-time capability, this delivers both functions properly. It’s ideal for diving instructors working internationally, technical divers who travel to different dive sites, or professionals who combine underwater work with international business travel.
