Any self-proclaimed field watch enthusiast and connoisseur would have at some point in time come across the quartz-powered CWC G10 and its iconic battery-hatch case-back which makes it possible for anyone with basic motor skills to easily swap the battery inside. (Which is of course found on many Timexes and that since the dawn of quartz horology.) This is the case of a tool watch distilled to its essence from a visual standpoint and mechanically dumbed down so that it is reliable and extremely serviceable on the battlefield or at home. It further constitutes the perfect starter watch for any budding enthusiast and sole field one for any amateur of military timekeeping devices for it is said to be durable and it is evidently very easy to read. Which is basically what we ask from a straightforward field watch and what makes them both timeless and a challenge to reinvent as we saw recently with the namokiMODS NMK09 and Delhi Watch Company Terra Titanium. A challenge not too tall for BiGi Design. 

Ah ah. 

We first met the American company through the study of the Ti Field Watch Stonewashed, an RZE-powered titanium utilitarian timekeeping device which constitutes BiGi’s ideal formulation for such time-measuring instrument. It is legible, functional, quite handsome if I would say so myself, and well-priced at $499 USD given the luxurious suite of specifications it is endowed with. However, it offers more than some might be looking for in a field watch and thus BiGi decided to conceptualize a simpler version of it in the Base Line Field Watch. Fewer dial ornamentations, the most basic complication of time + nothing, and the addition of a quartz-powered caliber anyone can re-juice then thanks to a battery hatch located on the case-back. Its price has also been simplified to $199 USD which seems more than appropriate for what you get—which is a lot. You know me, I love a simple field watch and I know you too—you’re the same which is why you’re here about to discover a superb new example in the genre. 

Specifications 

After studying so many field watches over the past six years I believe I have a pretty good understanding of what makes a good example of it from a technical point of view. That is in the microbrand realm of things of course which is where we find the best value field watches and those which I think are appropriately priced for what they are supposed to be—straightforward tool watches deprived of engineering frills and visual maximalization. (If they weren’t this way then I would be yet another journalist writing about the Rolex Land Dweller or Tudor Ranger. Dear Lord.) Instead, you might be of the following opinion: a good field watch should be robust, affordable, and legible, nothing more and nothing less either. Field watches are indeed the horological epitome of less is more and more sucks which is why the BiGi Design Ti Base Line Field Watch—in black, it also comes in white—has everything it should have and none of what it shouldn’t. This is starting to sound a bit like my personal philosophy for life. Well. 

You might be surprised by some of its technical features but you won’t be surprised by its case material: sand-blasted grade 2 titanium all BiGi Designs’ watches are made out of and RZE’s specialty as you might already know. The Base Line Field Watch is therefore durable, scratch and corrosion resistant, and stupidly light clocking in at 54g on the provided two-piece canvas strap equipped with quick-release spring-bars, matching titanium buckle, and a leather backing for all-day wrist comfort. The strap is the kind which is a bit rough fresh-out-of-the-box but which softens over time the more deployments you go on or the more diapers you change. Moreover, the titanium case is equipped with a screw-in case-back and an intensely-knurled 6.8mm push/pull crown which endows the Base Line Field with a sufficient 100 meters of water resistance. As you know, the case-back is furnished with a battery hatch you can open using a coin (if you still have some) or carefully with a knife so you can easily replace the little thing. 

Whenever we speak about battery hatches we therefore speak about quartz-powered calibers which is what we find inside the titanium case: a sweep-second Seiko VH31where the seconds hand ticks four times per second instead of the usual one-tick-per-second rate of basic quartz movements, which has a stated accuracy of ±15 seconds per month and a battery life of roughly two (2) years. BiGi Designs describes the VH31 as a mecha-quartz caliber however I’m not sure this is actually the case as it doesn’t seem to come with any mechanical parts (please do correct me if I’m wrong) which some quartz-powered chronograph movements do. Whatever the case may be, the VH31 is reliable and satisfying to use due to its set-it-and-forget-it nature. Thus far then the Base Line Field Watch has good water resistance, a lightweight and solid case, and a reliable movement. What’s more? Excellent applications of BGW9 SuperLuminova on the hands and hour markers save for the collection’s logo at the twelve, and a flat and clear sapphire crystal. 

Design 

Maybe you will also agree that a core defining element of a good field watch is its everyday comfort as well as its fly-under-the-radar case and dial design. (Anything that would be extravagant wouldn’t fit field watches’ historical utilitarian leitmotiv.) On the first point, the grade 2 titanium is, as we know, light and durable, but it also wears supremely good despite its larger-than-ideal dimensions (for me) of 40mm in diameter, 48mm lug-to-lug, 11.2mm thickness, and 20mm lug width, because, again, it is light. Thus the Base Line Field Watch commands a visual wrist presence which is more demanding than usual, however offset by its superb on-wrist comfort especially once you have broken the strap in. (Pair it with a velcro-style nylon strap and it will be light as an angel.) In terms of design, the case is of course reminiscent of many RZE inventions: angular lugs, sand-blasting finish, straight flanks, and a slightly stepped fixed bezel profile. The case thus flies under the radar albeit it has personality. 

The dial is equally capable of flying under the radar whilst being extremely legible, so satisfying to read actually that I caught myself looking at it many times without the intention of knowing what time it is because it is so symmetrical and monochromatic. (Almost perfectly so.) Above it, we see two soft rectangular hands indicating the hour and minutes, lumed at their center and finished in sand-blasted alloy. They are accompanied by a matte-green needle-shaped seconds hand which gently pops from the matte black dial. (That is the exception to the full monochromatism of the latter.) On it, the hours are represented by a series of large batons and dots mimicking the brand’s logo, composed of gloss-white applications of luminescent compounds framed by thin white lines. At the twelve, there is the collection’s logo printed in lieu of a marker however not lumed as it was the case on the automatic field watch. (Boo.) At the periphery of the dial a simple minute track and the mention of the depth rating below the pinion. 

The Heart of the Matter

I for one believe we should applaud any brand which embarks on the difficult task of creating a basic field watch in 2026. (I think the BiGi Ti Base Line Field Watch was launched last year actually.) “Basic” in a positive way in the sense that it does what it's supposed to for a small amount of money, without truly breaking the mold for this genre of horology, and perfectly following in the footsteps of its numerous predecessors. $199 USD seems like little to spend today given the constant rise of most popular models and the risqué market entries of many new micro and independent brands which, just like that, ask more than a grand for their debut collection. And price hikes is a topic which is so popular right now on magazines, blogs, YouTube, and social media channels, that we could be conditioned to think that it is ok to spend more than we should for a good tool watch. I wholeheartedly disagree with this idea which is why, basically, I wanted to tell you about this BiGi because it offers something which is rare to find nowadays: an affordable, durable, and legible field watch. 

Nothing more, nothing less. 

Conclusion 

Visually and technically the BiGi Design Ti Base Line Field Watch has a lot to offer and $199 USD is more than a fair price to pay for it. And since it was designed with the intention of being the perfect field watch for anyone, both versions are readily available to purchase from the brand’s website at the time of publishing this article. This is just good news for folks like you and I who are into straightforward, reliable, and legible tool watches and who believe such types of horology should come with a price tag which prevents us from questioning whether or not we should buy it. It’s awesome ergo you ought to buy one.

Thanks for reading.
