UNDONE Basecamp Cali Black Automatic

by Brent Robillard

Affordable, customisable, and surprisingly well executed

There is a persistent idea among newcomers (and sometimes old hands) that watch collecting only becomes “serious” once you cross some arbitrary price threshold. Spend enough time around the hobby and you’ll eventually hear that sentiment repeated often enough to almost believe it. This is where brands like UNDONE offer a convincing counterargument.

Who are UNDONE?

Founded in Hong Kong in 2014, UNDONE has built its reputation on making mechanical watches accessible while giving buyers something that many larger brands still don’t: the opportunity to make a watch their own. UNDONE has woven customization into the company’s identity, allowing customers to configure everything from dial layouts and hands to casebacks and personal engravings. The result is a watch that feels considerably more individual than most factory-produced alternatives in this price bracket.

The Basecamp

The Basecamp collection takes a different approach than many of the brand’s more playful collaborations. Instead of licensed characters or bold graphic themes, the Basecamp looks toward vintage field and military watches, with the Cali Black Automatic drawing particular inspiration from one of watchmaking’s most recognisable dial layouts.

California dial

The California dial has been around since the 1930s, combining Roman numerals in the upper half of the dial with Arabic numerals below. Originally intended to maximise legibility, it has since become something of a cult favourite among enthusiasts. Whether you appreciate it for its history or simply because it looks unlike anything else in your watch box, it gives the Basecamp a distinct personality with echoes of the Rolex Bubbleback.

Case dimensions and details

Sized at 40 mm with a 48 mm lug-to-lug measurement, the watch lands in familiar territory for an everyday mechanical watch. A heavily domed Lexan polycarbonate crystal adds a generous helping of vintage character, contributing to the quoted 15 mm overall thickness. Inside beats the dependable Seiko-derived TMI NH35A automatic movement, while 100 metres of water resistance ensures the watch is more than capable of handling daily life.

What stood out most during my time with the watch wasn’t any single specification, but rather how cohesive the entire package feels.

The friction bezel deserves mention. Too often these bezels feel either loose or overly stiff, but the Basecamp finds a pleasing middle ground. Rotation is smooth, deliberate, and reassuringly secure. It isn’t intended as a professional timing instrument, but it is genuinely satisfying to use.

The dial is equally successful. High contrast, uncluttered, and immediately legible, it demonstrates why the California layout has remained relevant for nearly a century. Lume performance is perfectly respectable at this price point. It charges quickly and shines brightly, even if it won’t necessarily remain glowing until sunrise.

Case finishing is clean throughout. Personally, I would have welcomed a little more brushing to reinforce the tool-watch aesthetic, but that’s a matter of taste rather than execution. The polishing is evenly applied, transitions are crisp, and nothing about the watch suggests corners have been cut.

Perhaps the biggest surprise was the strap. Leather straps supplied with affordable watches are often little more than placeholders, but this one feels genuinely considered. The leather is supple straight out of the box, the taper is substantial, and it balances the proportions of the watch nicely on the wrist. I found myself with little desire to replace it, which is about as strong an endorsement as any factory strap can receive.

Final Thoughts

Viewed in isolation, none of these details is revolutionary. Taken together, however, they paint a picture of a company that understands where value really comes from. Good proportions. Honest finishing. Reliable mechanics. Thoughtful design.

The Basecamp Cali Black Automatic won’t compete with Swiss luxury brands, nor is it trying to. Instead, it serves a different purpose: offering an approachable mechanical watch with genuine character at a price that leaves room in the budget to continue exploring the hobby.

That may be UNDONE’s greatest strength. The company understands that every collector starts somewhere, and there is no reason that first—or fifth—mechanical watch can’t be thoughtfully designed, well assembled, and enjoyable to wear. For less than US$500–the model sent in for review retails for only US$325–the Basecamp Cali Black Automatic makes a persuasive case that good watchmaking has become more accessible than ever.
