I like divers for their readability, luminescence and resistance, especially those that keep an original and elegant design. 
This model, discovered at a watch fair, has all these qualities. 
Originally delivered with a black nylon strap and a leather one, I bought a steel strap in addition. 
An additional nylon was offered to me when I purchased it.

Original and elegant diver

I was looking for a watch with an ice blue / sky blue dial, but after some disappointments following purchases on photo I discovered this F77 SMOKED BLUE with a textured dial. 
I was immediately seduced by the photos but without being able to try it. This time I was not disappointed, this watch is much more beautiful "in real life" than in the photo. Its dial associated with its sport chic case are magnificent! The domed glass and its finesse add even more elegance to this model. 
I use it as a "dress" watch when my divers don't fit under the shirt.

Gorgeous 

I discovered Ollech & Wajs by first being interested in another watch of the brand, the C-1000, but while searching for this model I discovered this Ocean Graph. 
It is just as resistant, of identical dimensions and with the same strap that I love, but with a much more "fun" look. 
Its Atlantic blue dial is magnificent, its decompression bezel is splendid (admittedly illegible for me without glasses, but not being a diver, only its aesthetic aspect matters to me). 
The contrast between the blue of the dial and the orange hands also pleased me a lot. 
This watch fears nothing, not even scratches, thanks to its entirely brushed finish.

Beautiful, durable and readable

This watch, water-resistant to 300 meters, is extremely elegant. It offers very good readability day and night. In full sunlight, the sapphire bezel is magnificent with its red indexes. In the shade, the touches of green luminescence are most beautiful. Its precision is excellent, measured between 0 and +2 seconds per day on my copy.

Elegant and precise

I particularly like the originality of this watch, both for its dial and its very discreet GMT hand. I appreciate the GMT function for its 24-hour display, more for its aesthetic aspect than for my personal use, not being a great traveler. Here, reading the time is quick because it is not disturbed by a GMT hand that is too present. 
I also like its elegance and its relative finesse. 
Another originality is the association between GMT and diving function. 
The luminescence is excellent while maintaining a beautiful elegance. 


Original and precise GMT watch

I went for this OW Astrochron because I was looking for a chronograph whose aesthetics I liked, well finished, automatic, original and technically accomplished. Its exceptional resistance is a plus even if I do not intend to use its guaranteed water resistance for 500 meters. It is a kind of hybrid between a diving, sports and exploration watch. 
It is precise with an average deviation of +4 seconds per day for my copy. 
Its thickness is not annoying and sits perfectly on my wrist. 
A button dedicated to the quick adjustment of the date is also very appreciable. 
I really like its luminescence and its date window, very well integrated into the design of this watch.

Beautiful chronograph

The Longines brand was created in 1832 by Auguste Agassiz in Saint-Imier, located in the Swiss Jura. First registered watch brand, Longines shares a large part of its history with the rise of sports, the two worlds having in common values ​​of tradition, precision and elegance. This DNA has allowed the brand to launch models that have marked watchmaking history, such as the Longines Chronograph 13ZN or the Longines HydroConquest.
The current Longines range offers classic watches like the Longines DolceVita or the <a href="https://www.dialicious.com/en/longines/master_collection">Longines Master Collection</a>, as well as sports watches like the<a href="https://www.dialicious.com/en/longines/legend_diver"> Longines Legend Diver</a>,<a href="https://www.dialicious.com/en/longines/conquest"> Longines Conquest</a>,<a href="https://www.dialicious.com/en/longines/spirit"> Longines Spirit</a>,<a href="https://www.dialicious.com/en/longines/hydroconquest"> Longines HydroConquest</a> or<a href="https://www.dialicious.com/en/longines/ultra-chron"> Longines Ultra-Chron</a>. Longines has also been involved in polar and aerial expeditions, providing precise measuring instruments to explorers to calculate longitude and latitude. Indeed, it is notably the brand which was chosen by Charles Lindbergh to design a navigation watch during his famous transatlantic flight in 1927. The watch, called <a href="https://www.dialicious.com/en/longines/lindbergh_hour_angle">Longines Lingbergh Hour Angle</a>, was used to determine the position of Lindbergh's plane during the historic flight.

Bought less than 2 years ago, a real favorite diving watch with a vintage look that I immediately liked. Waterproof to 300 meters, incredible precision thanks to the in-house movement caliber L836.6 with automatic winding, certified Ultra-Chronometer by TIMELAB, magnificent hands, perfect readability except perhaps at nightfall (but perhaps due to my aging eyesight) diameter of 43mm for a thickness of 13.6mm so yes it is a beautiful beast but I find that on my 17.5cm wrist it suits me quite well. The black bezel turns gray depending on the light and I still never tire of watching the second hand slide at crazy speed on this magnificent, very refined dial. 
Index of the cardinal points in applique. Last thing, the watch is a little heavy but not unpleasant to wear.

Details

I succumbed to the shape of this watch that I find very original. While listening to Julien in an episode of Petites Montres Entre Amis, I told myself that it was time for me to look at vintage Longines more closely and in particular the Ultra-Chron collection recognized as one of the very first watches equipped with a 5Hz caliber. While searching on the various second-hand watch sales sites, I discovered this one with a unique shape! The hands are original - if we refer to the ads of the time - the striated dial, the crown at 4 o'clock gives it an asymmetrical side... It has just joined my asymmetrical collection with the Zodiac Olympos and the Omega Constellation D-Shape! It would have been even more successful without the date which impacts the purity of the lines... Note an outdated configuration with a monobloc case which opens by removing the glass... I'll leave that to the watchmaker who will service it in the coming days 😎

A question of form but not only 🤷‍♂️

A watch that combines charm and period know-how, this Longines Ultrachron ref 7826 dating from 1973 reminds us that sometimes certain vintages deserve a lot more attention.

The horns are very angular with a slight chamfer on the inside.
The rather thick stick indexes have multiple facets, the dial is cream-colored and is crossed by a line called "target", the Longines logo and the ultra-chron symbol are applied.
The domed glass obviously gives us the feeling that the edge of the dial is curved, which it is not.
The case, case back, hands and indexes are in 18k rose gold, which contrary to appearances remains rather discreet and not flashy surely due to the very light brushing of the case.

To finish it is a very classy watch, that I wear sparingly during special events, the noise of the caliber 431 very singular and hypnotic is similar to a small "machine gun".

It did not take less to become my dress watch par excellence.
