Off the Cuff: Seaholm OffShore

Seaholm is a brand founded in 2013 by Todd Adams, a former executive of the Yeti company which has famously brought modern and rugged adventure coolers to the world of outdoorsy people. The brand released three models all at once—a field watch, The Rover, a chronograph, The Flats, and a diver, the Offshore, the latter being the model we are taking a look at today. The brand so far has you covered for all types of adventures you could go on, and as we will see, the OffShore packs a punch of neat features that make a it a reliable tool watch.

The case of the OffShore, just like the two other models, comes in at 41mm, with a lug-to-lug distance of 50.5mm, a height of 14.5mm, and a lug width of 21mm. The entire case is finely brushed, so is the bracelet which is equipped with solid links and end-links and a diver’s extension. Inside the watch you will find a Sellita SW200-1 which beats at 28,800 bph (4Hz) and offers 38 hours of power reserve. The crystal is of the double-dome sapphire type which offers great resistance to scratches, and the dive-time bezel is made of a brushed piece of stainless steel. All in all, a solid watch with great specifications. However, the fun doesn’t stop here.

The OffShore has a depth rating of 200 meters and each watch is tested to meet the ISO 6425 requirements, making the OffShore a true diver which one could take on any underwater adventure with confidence. (I took mine on a 30-meter dive and it worked as it was supposed to. I know, it’s not the Mariana Trench though!) Furthermore, the OffShore has also been tested and engineered to resist magnetism up to 33,500 a/M (the ISO requirement is 4,500 a/M) and to withstand a 10-foot (3m) drop without suffering from any time deviation. That’s a lot of features built-in this watch that are not commonly found in microbrands.

So the OffShore has impressive specifications and the company went out of its way to ensure that their watches could be as tough in reality as they appear to be on paper. What sets Seaholm apart is that the company was founded by an outdoorsy guy for whom having a tool watch truly built to specifications was important. Todd thought of which functions the watch should fulfill before getting any drawings done. He thought of the man and woman who, like him, needed a sturdy watch to do their jobs–be it working on a construction site, spear-fishing, or commercial diving. Todd is an outdoorsy man who needed a watch built for that purpose and so in 2013 he started researching the different ways in which a watch could be made for the outdoors.

The result of his search led to the creation of three over spec’ed models the company released all at once. Anyone can go on Seaholm’s website to take a look at their White Paper which describes the testing they’ve conducted and the technologies they have developed or used to ensure that all of their watches are water resistance to 200 meters, anti-magnetic, and anti-shock. As we saw above, they test their watches to meet the ISO 6425 requirements to ensure the watch can indeed go 200 meters deep in the ocean and function normally. Furthermore, the OffShore, just like the Flats and Rover, is equipped with an ARMCO iron cage that protects the movement, dial, and caseback against magnetism. (As we mentioned above, it protects the watch up to 33,500 a/M, which is quite impressive.) 

Lastly, Seaholm developed its own shock-absorbing mounts using Japanese materials and Swiss ingenuity to make their movement withstand a 10-foot (3m) drop without showing any deviation in time keeping. According to Seaholm, going through this type of testing–and engineering watches that could still tick after such a drop–was more stringent than getting the ISO certification due to the fact that a watch’s resistance to shock is generally theory-based, not clinically tested. Seaholm worked with a Texas-based company to do real-life shock tests. All of this is to say that Seaholm went out of their way to develop sturdy tool watches and to go through numerous tests to make sure that they live up to life’s test (pun intended) of water submersion and resistance to magnetism and shocks. 


While all of these specifications are impressive and guarantee that the watch can basically be used in any and all situations, it retails for close to $2,000 which is a hard bullet to bite for a first watch from a brand you may have never heard of. Microbrands typically offer a first model under the $500 mark and then work their way up to $1,000 as their models become better made and are endowed with designs that are more original. Barring a few exceptions (Monta, Vero’s first model…), microbrands’ retail prices generally stay under $1,000. As we’ve seen above, you will know that you are buying a very solid watch however much you will have to spend on it. 

A second quibble could be had in the extra layers of texts present on the dial. We often hear reviewers criticize Rolex for adorning their watches with too many lines of text, and the same is true of Seaholm. The logo can easily appear too large and the brand, it seems, which wanted to ensure you know how well-build their watches are, felt compelled to indicate “Diver’s 200m,” “Anti-Magnetic,” and “Anti-Shock” on the dial underneath the pinion. I find this unnecessary, however, I can only speculate as to the reason for this. Just like Rolex or Omega proudly indicate how well-built their watches are—for example, that they are “Superlative Chronometer” and “Officially Certified”–Seaholm did the same as a way, perhaps, to justify the $2,000 price tag.

Final Thoughts

If you are in the market for a sturdy tool watch and that you don’t mind the extra lines of text on the dial, then you are in for a treat with the Seaholm OffShore. I’d say that it is a true tool watch that I have not shied away from taking on any types of adventure. Along with the Serica 4512, the OffShore is the only watch I have taken diving, of all the diver’s I’ve had my hands on in the past two years. I felt comfortable doing so not because of all of the reassuring lines of texts on the dial, but because I knew—and could feel when handling the watch—that it could truly take a dive. There is something re-assuring about knowing that a tool watch in is also a tool watch in build like, and that it can perform well in any and all situations.

The Seaholm Offshore retails for $1995USD. For more information, check out the brand website.
