The NITE Hawk Night Fall is a very large but surprisingly lightweight tritium watch, combining a 51mm reinforced polycarbonate case with sapphire crystal, a Swiss Ronda quartz movement, 200-meter water resistance and T100 tritium illumination. I bought the Night Fall as my second NITE watch after the NITE Alpha Crest, and what stands out most in actual use is the combination of its low 70-gram weight and exceptionally bright T100 illumination.
The Hawk also has several details that distinguish it from similar lightweight tritium watches, including its deep-set dial, red seconds hand, screw-down crown and supple rubber strap. I also compared it directly with the Isobrite 3003, which is visually similar, and found the NITE’s illumination noticeably brighter.NITE Hawk Night Fall Specifications

A very large watch that does not feel very heavy
The first thing you notice about the Hawk is its size. At 51mm, this is not a watch that disappears beneath a shirt cuff, and the large case gives it a substantial presence on the wrist.
What surprised me was how little that size translates into weight. The reinforced polycarbonate case brings the watch down to approximately 70 grams, and on my wrist, which is over seven inches, I find the proportions work well. The large case also creates considerable depth around the dial, which is something I actually like about the design.
The bezel sits slightly above the crystal, almost like a raised rim around the dial. That should provide some practical protection for the sapphire crystal because the bezel is likely to encounter an impact before the crystal itself.
The lightweight construction also changes the character of the watch compared with a conventional stainless-steel case. When I want a watch with some physical weight, I reach for the NITE Alpha Crest instead, but when I want something large without carrying the weight of a large steel watch, the Hawk makes a lot of sense.
The dial has more depth than you might expect
The Hawk’s dial is set relatively deep within the case, and that is one of the visual characteristics I like most. Rather than having a large, flat dial filling the entire case, the surrounding structure creates a noticeable sense of depth.
In daylight, the smaller minute markings are not particularly prominent from a normal viewing distance. The larger five-minute numerals and the broad markers do most of the visual work, which gives the dial a relatively clean appearance despite the watch’s very large case.
The black dial also provides a strong background for the tritium markers and hands. Once the ambient light disappears, the illumination becomes the dominant feature of the watch.
T100 tritium is the star of the show
The Hawk Night Fall uses T100 tritium illumination, and this is where the watch really separates itself from many conventional tritium watches. NITE’s specifications identify the illumination as T100 Tritium GTLS, with green or orange illumination available depending on configuration.
In my experience, the illumination is exceptionally bright. I specifically compared the Hawk with the Isobrite 3003, and although the two watches are visually very similar, the Hawk is the brighter watch at night. That difference is immediately noticeable rather than something that requires a close inspection.
The red seconds hand is another feature I particularly like. The Isobrite’s seconds hand is black, while the Hawk uses red, and that small change gives the dial considerably more visual character.
The combination of the bright T100 tubes and the red seconds hand also makes the Hawk visually distinctive among the watches I have reviewed. It is not simply a large black tactical watch with tritium added to it; the illumination is a major part of its identity.
Sapphire crystal
The Hawk uses sapphire crystal with anti-reflective coating. That is an important specification on a watch of this type because the crystal is one of the components most exposed to scratches during everyday use.
The slightly raised bezel is also useful here because the case design places a physical structure around the crystal. I like that combination of sapphire and bezel protection because it addresses two different types of wear: sapphire provides excellent scratch resistance, while the raised bezel helps shield the crystal from direct impacts.
Ronda 715Li quartz movement
Power comes from the Swiss-made Ronda 715Li quartz movement, with hours, minutes, seconds and a date display. The published specification gives the movement a battery life of approximately 10 years, which suits the overall low-maintenance character of the watch.
Quartz is also a logical choice for a watch that is designed around practical, always-ready illumination. There is no need to wind the watch or keep it running through regular wear, and the long battery interval means that routine maintenance should be relatively infrequent.
The date window is positioned within the lower-right portion of the dial. It adds useful everyday functionality without significantly disrupting the large tritium markers.
Bezel and water resistance
The Hawk has a unidirectional rotating bezel and 200 meters of stated water resistance. Those specifications give it the basic configuration expected of a serious water-oriented sports watch, although the enormous 51mm case makes the Hawk’s overall character quite different from a conventional compact dive watch.
The screw-down crown is another feature I particularly like. In my comparison with the Isobrite 3003, the crown arrangement is one of the meaningful differences between the two watches, and the screw-down crown gives the Hawk a more substantial tool-watch configuration.
The rubber strap is excellent
The supplied rubber strap is one of the better aspects of the package for me. It is very supple and works particularly well with the large, lightweight case because it does not introduce unnecessary stiffness or weight.
The watch also came with a NATO strap. I like the NATO as an alternative, although I find the rubber strap more comfortable for regular wear because of its suppleness.
With 24mm lugs, the Hawk has plenty of strap presence, and the broad strap suits the proportions of the case. A narrow strap would look out of place on a watch this large.
UK design, Swiss components and Hong Kong assembly
One point on the original article needs particular clarification. The page originally introduced the watch as “British Brand – Swiss Made,” but the later section of the same article provides a more accurate breakdown: NITE’s design is in Christchurch, England; the movement and tritium illumination are Swiss components; and final assembly and quality assurance for the Hawk are generally carried out at NITE’s technical centre in Hong Kong.
That distinction is worth retaining because it is useful information for a specialist watch site. “British-designed” and “Swiss movement” accurately describe important parts of the watch, but they should not be combined into “Swiss-made” if the watch itself is assembled elsewhere.
This is also consistent with the comment reproduced on the original page, which specifically pointed out that the Hawk is assembled in Asia. The commenter did not present that as inherently negative, but instead identified the OEM manufacturing background as part of the watch’s provenance.
NITE Hawk Night Fall vs. Isobrite ISO3003
The Hawk immediately reminded me of the Isobrite ISO3003 because the two watches share a very similar overall visual concept. Both use large lightweight cases, black tactical styling, tritium illumination and a broad bezel, so they occupy a similar space visually.
The differences become more interesting when you actually compare them. The Hawk has the screw-down crown and red seconds hand that I prefer, and my experience is that its T100 illumination is noticeably brighter at night.
| Feature | NITE Hawk Night Fall | Isobrite ISO3003 |
|---|---|---|
| Case style | Large lightweight tactical design | Similar lightweight tactical design |
| Illumination | T100 | T100 |
| Seconds hand | Red | Black |
| Crown | Screw-down | Not screw-down |
| Night-time impression | Brighter in my comparison | Less bright in my comparison |
| Overall visual character | Large, deep, highly illuminated dial | Very similar overall design |
This is not a case where one watch is dramatically different in concept from the other. Instead, the Hawk’s advantages for me are the details: the red seconds hand, screw-down crown and stronger observed illumination.
What I like about the NITE Hawk Night Fall
The strongest feature is unquestionably the T100 illumination. I have reviewed a number of tritium watches, and the Hawk stands out because the illumination is so prominent in darkness without requiring any charging or activation.
I also like the combination of the enormous case and very low weight. A 51mm watch sounds excessive on paper, but the 70-gram construction makes it much easier to wear than the dimensions would suggest, particularly on a wrist over seven inches.
The sapphire crystal, screw-down crown, 200m water resistance and long-life Ronda quartz movement give the watch a practical specification set. None of those features is unusual by itself, but together they create a watch that is clearly designed around durability, low maintenance and nighttime readability.
What I would consider before buying one
The biggest consideration is size. At 51mm, the Hawk is a genuinely large watch, and although the low weight makes it comfortable for me, the same proportions will not suit every wrist or every style of clothing.
The other consideration is that the lightweight polycarbonate construction gives the watch a very different feel from a steel watch. I enjoy that characteristic, but someone who equates quality with the physical heft of a stainless-steel case may prefer something such as the NITE Alpha Crest.
The illumination is also a major part of what makes the Hawk distinctive. If you are specifically looking for a tritium watch with very strong T100 illumination, that is an advantage; if you simply want a conventional everyday watch with modest nighttime visibility, the Hawk is considerably more watch than you need.
Is the NITE Hawk Night Fall a good tritium watch?
For me, the NITE Hawk Night Fall is particularly compelling if the priorities are bright T100 illumination, low weight, sapphire crystal, quartz reliability and a very large case. My own experience confirms that the illumination is the standout feature, and the lightweight construction makes the 51mm dimensions much easier to live with than expected.
It is also a good example of why tritium watches should not be evaluated from specifications alone. The T100 designation tells us what illumination system is being used, but actually seeing the watch in darkness reveals how much of a difference the implementation makes.
Final thoughts
The NITE Hawk Night Fall is a very large watch, but it is not a heavy watch, and that distinction is central to its appeal. The reinforced polycarbonate case keeps the weight to about 70 grams while the 51mm dimensions give it a substantial presence on the wrist.
For me, the combination of the deep dial, sapphire crystal, red seconds hand, screw-down crown and especially the T100 illumination makes the Hawk one of the more interesting NITE watches I have worn. My comparison with the Isobrite 3003 also reinforced the fact that the Hawk’s illumination is not merely a specification on a sheet; it is one of the first things you notice when the lights go out.
The watch is not going to suit everyone because 51mm is a serious commitment in case size. On my 7+ inch wrist, however, the proportions work, and the low weight makes it surprisingly easy to wear.
Nice site, and great writing !!! Finally people are taking tritium watches seriously.
Just one thing, that watch is assembled in Asia, just like Protek, Isobrite, Deep Blue, and many alike. But it’s not a bad thing, it was made in one of the best tritium watch OEM factory, the only one I will choose if one day I decide to start a brand.
