From Erebus

The Erebus Titan is the undisputed king of the Erebus diver range. The largest and most impressive Erebus diver to date, the Titan carries the highest specs of any of our family of watches. Built for collectors who don’t shy away from bold statements, the Titan is impressively large and imposing at 44mm but also surprisingly wearable, with a compact lug to lug of well under 50mm. Designed to withstand the depths with 500m water resistance, the Titan comes with Viton® gaskets and a helium escape valve to complete its genuine deep diving credentials. The Erebus team is pushing boundaries with a host of firsts: a full lumed dial version, lumed crowns at 4 o’clock for comfort and easy access, a pair of stealthy DLC options, and hardness coating on all cases and bracelets for enhanced durability. Despite its hardcore specs, the Titan doesn’t skimp on refinement. With a two-piece applied logo and lumed applied indices, this incredibly capable watch looks strikingly handsome on wrist. Dial choices are off the charts. Choose between rare volcanic obsidian or meteorite mineral dials, fumé sunburst or granular dials, all choices complemented by all brushed, fully lumed ceramic bezel inserts. The Titan backs up its incredible value for money, with incredible performance, fantastic legibility, and the long-term reliability of TMI’s stalwart NH35 movement. Finally, a custom designed super engineer bracelet featuring quick release and lots of micro adjustment, rounds out what is the most complete diver watch package Erebus has ever produced. Erebus has produced the microbrand world’s ultimate value diver. The only question is, are you ready for the Titan?
