Prometheus Trireme review
Prometheous is a small Portuguese boutique watch manufacturer, founded in 2008.
The Trireme from Prometheous is a vintage style divewatch with a 300 meter water resistance and a ETA 2824-2 movement inside.
The Trireme arrives in a black travel case with white stitching, and the Prometheus logo on the top. The watch was held by two elastic bands, and in the top part of the case is another compartment closed with a flap. This compartment also has two elastic bands under the flap so it could probably be used to hold a second watch while traveling.
The Trireme is available in a few different configurations. This watch is the white dial sword hand version. For the Trireme the configuration choices are between a black or white dial, with sword hands or plongeur hands.
The Trireme design is based on popular designs from the 1970´s according to the companies website, probably referring to designs by Omega and the likes.
The price of the Trireme is 409 euros or approx 548 US $ for people residing outside the EU, and 495 for people inside the EU. (free shipping worldwide included in the price)
The watch is covered by a two year warranty.
The Trireme has a 42.5 mm wide and approx 13 mm heigh made from 316l stainless steel case. The case has very straight lines, quite different than you see with most watch cases today. I like this design as it really grabs attention and those around me liked the different look of the watch.
The lugs in the watch are 22mm, a very common size on dive watches, so its easy to get additional straps if desired, the lug to lug distance is 50 mm.
The lugs are hidden under the case of the watch, as you can see here, fits well with the design of the watch.
As with most watches with the lugs hidden in the case the is less space around the spring bars making it a little more difficult to use very thick Nato straps, but I was able to use rather thick quality Maratac Nato straps without problems with the Trireme.
The Trireme is close to 207 grams with all links on the bracelet, but closer to 190 grams after I removed three links for the watch to fit my wrist.
The bezel on the Trireme is a 60 click sapphire unidirectional bezel with minute markers in C3 lume. The bezel has individual minute marks up to 15 minutes, and in five minute intervals after that.
The bezel has very solid clicks, and the bezel and dial markers line up perfectly on this watch.
This version of the Trireme has a white dial with lumed hour markers. The trireme has a date window at the 3oclock position, with a white background and black text, fitting the dial very well.
There is minimum writing on the dial, just the Prometheus logo and Swiss made.
The hands are sword hands with a chrome or silver boarder around the luminous c3 material.
The black dial version of the Trireme also looks very good.
The case back is a screw down case back with a very nice Trireme boat engraving, as well as the company name, water resistance, swiss made and serial number information.
Crown is a screw down crown signed crown, and the case acts are crown guard as you can see.
The crown is approximately 6 mm and has rather shallow ridges, but due to the cutouts in the crown guards down from the bezel and up from the case back you will not have a problem getting a hold of the crown in normal circumstances.
The Trireme has a stainless steel bracelet with a screwed link design, and four micro adjustment positions for minute adjustments to the bracelet size.
The bracelet has a signed clasp and a safety.
One thing to note for wetsuit divers is that there is not a diving extension on the bracelet, so divers that plan on using the watch to dive and wear it over a wetsuit might consider buying an additional rubber strap or NATO strap or something like that. And as you can see later on in the video the watch looks very good on different types of straps.
For us non divers this is really not an issue in my opinion.
To remove links you need a small screwdriver, but the convenient thing about the Trireme bracelet is that the screws screw into the links themselves so you only need one screwdriver to unscrew the screws
(many manufactureres use screw systems where you have an outer threaded screw that goes into an opposite internally threaded screw cap, so you have to use two screwdrivers, otherwise the screw will simply turn inside the link without loosening)
The C3 lume on the trireme is very good, and lasts for a few hours in a dark room. The hands and hour markers on the dial are brighter and last longer than the lume on the bezel.
The ETA has been running about 2 seconds fast every 24 hours, something that is really good for a mechanical movement.
The Trireme is a great watch for the price, where you get an automatic EYA movement, C3 lume and sapphire crystal and bezel in a 300 meter water resistant vintage style case.
The watch works well in formal and informal situations, and can be worn with well with Nato straps as well as other straps.
The lack of a divers extension should be taken into account for people that wetsuit dive, but does not really matter for non divers.
The review is finished, but below are a few picture of the Trireme on different straps.
Thanks for reading.
