Ternos professional 500m diver automatic 42mm black 16155950



Some watches don't have an easy time of it. On one hand, they have vital functions to perform, while retaining a characteristic allure on the other. Many watches find it hard to rise to this often a somewhat contradictory challenge. Not the case with the redesigned Ternos Professional TT from DAVOSA. This timepiece is a consummate professional and easily accompanies the wearer down to depths of up to 500 meters. And after punctually resurfacing, it makes a truly eye-catching statement on the wrist.

Beautiful looking watch, built like a tank

I bought my Davosa Ternos Professional 500m from the official online retailer Aysco, LLC. The team at Aysco, LLC went over & above to make me happy price-wise & they also made sure that they had exactly the watch I was looking for - black dial, black bezel/lunette, 500m water-proof. It took only 2 days to arrive at my door-step - delivered very efficiently by UPS. The wactch was very well packaged - the original watch box was shrink-wrapped to a sturdy piece of cardboard inb the shipping container ensuring that it would not move during transportation. I needed a really sharp knife to tear the plastic wrap. The actual watch box is very well made - glossy piano black. Upon opening, there was the watch I wanted! The complete watch was wrapped in plastic - dial top & bottom, braclet, clasp in blue plastic & a paper insert at the open-close so that there would be no finger nail scratches. Took a while to wrap all that plastic & I could not get it done fast enough so that I could try on the watch!
The watch is big - 42mm - that is the max diameter for my 7" wrist. Heavy - it's heft reminds me of another dive watch I've handled. The sapphire-domed crystal looks thick (for the 500m water-proof) & limits visibility from an angle when I turned my wrist to get a sideways look at the watch. I suppose this is normal. The dial looks great - black with applied markers & the inverted triangle at 12 o'clock that U wanted so badly. Love the mercedes hour hand, lollipop seconds hand & long minute hand that reaches to nearly the circumference.
Beautiful glossy black ceramaic bezel. Turning the bezel was difficult. This is one of two gripes I have. Maybe it's brand new & needs several turns of the bezel to get it working smoothly? I could feel the metal bite into my fingers. The bezel had a little play in it - the bezel inverted triangle is just teeny-weeny bit off from the 12 o'clock marker on the dial (not talking about the inverted triangle on the dial but the vertical marker at 12 o'clock on the dial). I t became apparent when I looked at the lume in a dark room - lumed dot on the 12 o'clock is just a hair off & to the right. I decided to ignore this as the rest of the watch is really very nice.
Very thick/chunky bracelet links that can take the weight of the hefty watch. Adjusting them to size is a breeze - I needed a small flat-head screw-driver. Thankfully no push pins in the bracelet! There are 4 micro adjustments in the clasp to make the fit perfect - I personally did not need those adjustments.
Nice clasp but I would say that it is not the strong point of this watch. I own cheaper watches that have a much better clasp action. Nevertheless, the click upon closing is reassuring.
The crown is nice & big - very easy to handle & smoothly unscrews. I had a little trouble pulling out the crown to position 2 to set the date. A few tries & I was successful in doing a quick-set of the date. The movement the ETA 2824-2 - Davosa's internal version of it. It's a hacking movement so when the crown is in position 3, the seconds hand stops & you can set the time to, say, NIST. Winding the watch with the crown in position 1 had a very nice buttery smooth feel to it. I would the dead-stopped watch about 30 time. I was apprehensive of over-winding it. Not sure if the 2824-2 has a clutch that prevents over-winding? I hope so such that it's idiot-proof! Nice action screwing back the crown.
I've been wearing it & it's a pleasure so far. It's ticking well & the date is correct. I have not measured the accuracy - that's my next to do. I've been admiring it so far...
I do like the fact that it does *not* have a cyclops at the date window. My choices for a homage watch were limited since I did not want the cyclops. Personal choice. YMMV.
Overall I am satisfied with my Sea Dweller homage watch. A few niggles but nothing I could overlook in the grand scheme of things. I would recommend this watch - it's best value is to buy it at a discount . If you are to pay full retail for it, then I would hold Davosa to a higher standard. if I look around and see the competition.
