Havaan Tuvali is a brand new micro watch brand from Eric Yeh of Taiwan. This is his first watch currently being offered for purchase. The brand name comes from the Taiwanese aboriginal language meaning “the deer’s sunset”. This refers to sun down, when the ancient people believed that as the deer came out of the forest to forage for food and water, it was the time to finish up their work for the day. This was in some ways how the people told time. The company’s logo is a flying fish, a symbolic fish for these people.
Offered in four color combinations, it is a solid pilot watch that combines unique characteristics that I have not seen previously. The watch has an external bidirectional slide rule bezel with a unique sub second dial and it has sapphire crystals front and back with a 450 meter water resistance rating. The watch combines an all 316L stainless cushion shaped case, SuperLuminova C3 hands and markers, a Swiss Sellita automatic movement and a few other special touches, normally not found at this price point.
For this review I have the Blue/blue model which has a blue outer and silver inner slide rule dial and a blue face. All Squadron One watches come with a fine stainless link bracelet as a well as a brown calf leather aircraft/racing style strap. I am reviewing the watch with the stainless bracelet. This cushion case design measures 44mm in diameter, 15 mm front to back, 52 mm lug to lug and 22 mm between the lugs. i have found that most pilot watches are quite a bit smaller than this watch, which has an usually high 1500 feet water resistance rating.
The flat sided case has a completely brushed finish except for the short curved lugs and the adjacent lug face, which are polished. The solid three link bracelet is polished except for the brushed center links and the back of the links. The solid (not stamped) clasp links have a matt brushed finish, as does the face of the signed, stamped clasp. The company logo is engraved on the clasp as well. The locking outer flip lock portion of the clasp also has a polished finish. The two o’clock gear edged crown is among the most recessed I have seen, measuring 6 mm in diameter by 3.5 mm thick. The crown’s face has a polished and etched jet plane on it. The crown is easy to operate, despite it’s low profile.
The brushed stainless, beveled, screw down exhibition case back is unusually well done due to it’s very readable engravings and by using a sapphire crystal. The Swiss made Sellita SW290-1 automatic movement is well displayed and has a nicely engraved and etched rotor. The movement itself is 31 jewels, 28,800 vph and has a power reserve of 38 hours with hacking and manual wind capability. It is rated a minimum accuracy rate of +/- 12 seconds per day in the standard model, which is much better than most automatic movements found in watches at this price point. My example has been accurate to COSC standards, which I think is remarkable at this price point.
The bidirectional slide rule blue with white lettering outer bezel is excellent, requiring both a fair amount of pressure to turn as well as feeling very smooth and solid. The inner fixed stainless finish bezel with black lettering contrasts perfectly. Both bezels appear to be carefully engraved and give off a true tool like patina. I won’t go into how this slide rule bezel works because I honestly do not know how to use it. The polished coin like bezel edge is both comfortable and provides a good grip at the same time. The 3 mm thick raised beveled edge, flat sapphire crystal is antireflective as well.
Four numerals and seven indices on the blue face are finished with Superluminova C3. Claimed to be the highest performing phosphorescent pigment currently in use today, it is a recent development, only invented in 1993 by Memoto & Co. Ltd of Japan. This strontium aluminate based lume greatly out performs and is much safer than the earliest radium lumes or the later zinc-sulfide lumes. The black cathedral minute and hour hands contain this lume as well, though I would prefer that these hands were both wider and longer.
The lower left portion of the watch dial contains a unique black flight instrument like display with a thin red second hand finished with white lettering. The red hand counts off seconds in one complete run around the display, 30 seconds at time on the top half of the display. This type of second hand is definitely harder to read than a conventional second hand, but at the same time it accentuates the pilot/aircraft vibe of the watch. The orange and white vertical racing stripes running through the second hand display give off a retro automotive look to the watch. The black on white circular 4:30 date window is both easy to read and unobtrusive, as are the minute markers. The printed white brand name in the upper right portion of the dial fits right in.
This watch is not a typical pilot watch that normally do not offer the slide rule function or the high water resistance rating. It has an automotive and even a boating look to it while at the same time maintaining very high quality throughout. It is solid, substantial and reasonably comfortable. Currently this watch is offered in four color combinations directly on the Havaan Tuvali website for $399 USD. I think it is an excellent value. www.havaantuvali.com
