It might not be the oldest player on the revered Glashütte block of Saxon watchmaking, but Tutima has consolidated an excellent reputation for resilient military-inspired chronographs (Flieger) and hyper-utilitarian dive watches with formidable depth ranges coupled with accessible prices. It also produces more upscale watches in true Glashütte tradition, like the Tempostopp hand-wound flyback chronograph or the exquisite Patria Small Seconds. Loosely grouped under the M2 collection, Tutima offers a wide range of models, running from 300m water-resistant chronographs like the M2 Pioneer Chronograph  to the beefy 500m water-resistant dive watches divided into the M2 Seven Seas collection in titanium and the M2 Seven Seas S collection in stainless steel. The latest models to join the M2 Seven Seas S – which stands for “steely, sporty & spectacular” – shrink from the regular 43mm case size to a 40mm diameter case and come with attractive gradient dials in four colours.

Rugged divers

The four releases in 40mm cases with a height of 12.5mm are not novelties. Although there are more 44mm x 13mm M2 Seven Seas S models in the collection, there are also 40mm case options, including this attractive black PVD case model with a green gradient dial. Its dimensions may be more compact, but its utilitarian dive watch spirit is intact. The stainless steel case has a solid screwed caseback and a threaded crown flanked by crown guards to ensure the water-resistance of 500 meters / 50 atmospheres. In addition to the solid caseback is a 2.5mm-thick anti-reflective sapphire crystal over the dial. Most of the case surfaces are brushed to underscore the sporty spirit of the diver, with a few polished areas for contrast.

The knurled bezel is unidirectional as a genuine dive watch, with a raised luminous dot at noon and a scale marking the first 15 minutes. The models with black and green dials have matching coloured ceramic inserts in the bezel with silver markings, while the red and blue dials have brushed steel inserts with raised markings and the mandatory luminous dot at noon.

Four dial colours – blue, red, green and black – expand the M2 Seven Seas S collection, all with an attractive dégradé or gradient effect, meaning that the colour is lighter in the centre and intensifies as it reaches the periphery. The applied indices and the baton-style hour and minute hands are treated with Super-LumiNova; the lollipop seconds hand (red on the green and blue dials) also has a luminous plot. The index is truncated at 6 o’clock to accommodate the date window with a white background and black numerals.

Rugged movement

The M2 Seven Seas S is powered by Tutima’s calibre 330 based on an ETA 2824 automatic, a proven workhorse that’ll last a lifetime with periodic maintenance. It has 25 jewels and beats at 28,800vph (4Hz) with a 38-hour power reserve. Functions include central hours, minutes, hacking seconds and the date.


The black and blue dial versions of the Tutima M2 Seven Seas S MariTimer come with brushed stainless steel bracelets with folding clasps and retail for USD 2,350. The green dial comes with a green leather strap with a rubber lining and green stitching, and the red model comes with a black leather strap with a rubber lining and red stitching; these retail for USD 1,980.

  1. Quite nice especially in blue/silver, would have been perfect in titanium and no date configuration. The bracelet looks very similar to Sinn, would have been nice to have a picture of the clasp, Sinn’s clasps are functional but not the greatest looking ones…

  2. What if a 40 mm day-date Valjoux 7750 chrono would follow suit – possibly with the central minute counter re-build?…
