Watch companies’ names either come from the watchmakers themselves or have some symbolic meaning to the brand. I’ve often wondered what Corum stood for. It turns out that Corum is a form of “quorum, which is the minimum number of people required to gather and make a valid decision. Okay, now that I know I’m still not sure of the horological significance, but no matter. I better understand what they’re going for with the key. Pointing to the sky, it represents mysteries to be unlocked and resolved and the exploration of new frontiers. It also implies the quest to master time. Now that we’ve got that cleared up…
Corum has been sailing the high seas for over 50 years, presenting the first Admiral’s Cup watch in 1960. In fact, they have the distinction of producing this first ever square waterproof watch. While the Admiral’s Cup certainly could fare well on the high seas, it wasn’t equipped to take an undersea adventure until 2010 with the introduction of the Deep Hull 48.
Corum now expands the Extreme line of this collection with the Admiral’s Cup Seafender 48 Deep Dive model rated to 1000 meters. When the ISO Standard of 100 meters/300feet qualifies a watch to wear the moniker “diver” then you know the Seafender 48 Deep Dive can plunge into the ocean further than 99.9% of people will ever go, so it’s never out of its element in either land or sea.
This isn’t a watch for wimps. The 48mm case, made of titanium to lighten the load, features a helium escape valve at 9:30, while the dial pops with orange accents reminiscent of a Halloween pumpkin. Matching orange Superluminova coats the hands to improve visibility in low light conditions. Like other Admiral’s Cup watches, it also features a representation of the international nautical flags around the flange that boaters use to communicate with each other.
Automatic Caliber CO947 powers this chronometer grade watch with a 42-hour power reserve that displays hours, minutes, small seconds at 9 o’clock and the day and date at 3 o’clock.
The Admiral’s Cup Seafender 48 Deep Dive offers a choice of two different versions: a 200 piece edition of the titanium case with the orange accents or a 100 piece edition of a PVD blackened titanium case and 18-carat red gold bezel. Both strap too the wrist with a rubber strap and titanium pin buckle.
Meehna Goldsmith's fascination with timepieces began with her parents' antique grandfather clock, whose harmonious ticks and chimes echoed throughout the house during her childhood. 
Given the alleged lofty price, & ruggedness, I feel this watch should sport a steel or titanium bracelet to deal with the ravages of scraping against coral, bashing into seawrecks, & possibly having to punch attacking sharks in their snouts. The great Severin Wunderman actually did wonders for Corum during his tenure, & he is greatly missed. Were you aware he was married to actress Gail O’Grady in 1987, & divorced that same year? I liked Corums from yesteryears, but they’re becoming too upscaled for average buyers, & that is not a positive development.
In my opinion divers watches need to be a bit more robust. But I realy like the watch. Great to wear during the summer and on holiday. Safe to swim with and great looks!
