    Review of the Prometheus Jellyfish yellow dial @watchreport.com

    The Prometheus Jellyfish yellow dial has been reviewed @ watchreport.com

    You can find here a summary of review:

    Iím a big fan of Prometheus watches, so when they came out with their new Jellyfish diver I emailed them right away for a review. There arenít a lot of watches in this category, so letís dive right in with the specifications.
    • 14.4mm thick, 44mm wide, 47.2 at the 6.9mm crown.
    • 195g sized to 7.5″ wrist
    • 316L stainless steel case, sapphire crystal with inner anti-reflective coating
    • 90-click unidirection bezel with inset tritium tube
    • Tritium tubes on all three hands and hour markers. Green color except at 12, which is orange.
    • SII NE15A (6R15) automatic movement, handwinding and hacking, quickset date, 40 hour power reserve.
    • Signed, screw-down crown
    • Water resistant to 300m (990ft)
    • 3-link Oyster-style bracelet with screwed, solid links, solid end links, brushed throughout. Clasp is snap closure with signed fliplock and 3 microadjustments.



    Most of the tritium watches weíve reviewed have quartz movements. (See here for a list) There are several reasons for this: tritium-tubed hands require more torque from the movement, the additional cost of the automatic movement and reduction in durability compared to quartz. Recently weíve started seeing automatic divers with tritium: A new Luminox, the Christopher Ward Tri-Tech, Marathon GSAR and Deep Blue. To this short list we can now add the Jellyfish.
    One of the things I quite like about the Prometheus watches Iíve reviewed is their consistently uncluttered and readable dials and designs. A lot of new brands put lots of text on the dial; the Jellyfish has only a small logo and the brand name. Wonderful! Even the caseback is an etched Jellyfish, a nice change of pace from some of the macho model names Iíve seen.
    In the closeup here you can see how the tritium works. Tiny glass tubes, about 1mm across, are inset into the dial and hands. You have to peer pretty closely, from a normal viewing distance it looks like applied markers. Notice how the tubes increase the thickness of the hands, because of this the dial is set a bit deeper below the crystal and the rehaut is a few millimeters taller to make room.
    The Jellyfish is available with black, white yellow or blue dial. In white or black itís most versatile and would make an excellent do-anything watch. In yellow itís more of a casual timepiece, quite fun to wear.
    Tritium is interesting if youíre used to Superluminova. Not as bright as full-charge conventional lume, the constant brightness can be quite startling in the early hours of the morning. Paired with the black-on-yellow hands, and anti-reflective sapphire crystal, and this is a watch with outstanding day or night visibility and legibility.
    This is my first watch with the SII NE15A. Introduced in 2007, this is a competitor to the ubiquitous ETA 2824 and Iím quite pleased. Smooth to handwind, no rotor noise, fast date change, excellent timekeeping, good date wheel alignment, itís a great movement and in my opinion is at least as good as the competition Miyota 9015 and ETA 2824.
    The case and bracelet are brushed finish of very high quality. I like here how the crown guards extend all the way to the end of the crown and flow smoothly from the side of the case. You can also see how the bezel is nicely grippy and protrudes for easy usage. The crown is midsized a 6.9mm, and has an etched logo. Action is very smooth, though as you can see on the video you have to be cautious engaging the first thread. (Iíve only seen one watch that didnít have this problem; threading is just plain tricky.)
    Sized for my 7.5″ wrist, the Jellyfish is a substantial 195g. Not a heavyweight, but youíll notice it there. As with most, the weight of the bracelet balances it out nicely.
    Notice how you can read the time quickly, and how the date window at 4:30 is visible but unobtrusive. The uncluttered yellow dial reminds me a bit of the Halios Holotype,another nice design. Also note how they rotated the tubes at three, six and nine to make room for an Arabic numeral. Simplicity is harder than it looks.
    The bracelet is excellent, and at this price point I was taken aback. Screwed links, solid end links, signed clasp and lots of extra links, no squeaks or rattles here. The clasp is heavy gauge metal, with machined parts, fixed-length wetsuit extension and four microadjustments for a perfect fit. About the only thing I might change is a pushbutton release instead of snap, but thatís a pretty trivial detail.
    As suits a solid watch, the bracelet is non-tapering, which helps keep it from shifting around on the wrist. The brushed finish is low-key and businesslike.
    Notice how the clasp is low-profile; this is more comfortable for those of us that spend all day on a keyboard as it doesnít dig into the wrist.
    The bezel is great. Easy to use, even when wet, with 120 clicks and markers all the way around, plus tritium pip at 12.
    At this point you might question my enthusiasm for the Jellyfish, so I should explain that it costs just $345 (non-EU price). At that price, it has no competition, and the quality is amazing. You really cannot go wrong here.
    I personally like the cheerful yellow dial, but itís a less versatile color and would be a stretch to wear in a formal environment. More of a summer, casual-Friday look. The black or white dials would work better for that, or perhaps the blue variant.
    There arenít a lot of watches I can recommend like this one. The price is fantastic, the quality amazing, and the style is versatile enough for most occasions. A bit sporty for the truly dressy, if anything, the combination of automatic movement and tritium illumination also excels at starting conversations.
    Highly recommended.
    Our thanks to Prometheus for the review loaner.

    Love Watchreport.com!!! :)
    I now received my white Prometheus Jellyfish and so far, very happy with my choice! :)
    Had read and seen the video since itīs usually my first webpage to check when i turn on my computer, it was a nice surprise to see the Jellyfish since i was looking for a Seiko or another watch with a Seiko movement, especially if it had the NE15A movement ( also known as 6R15 ). Portuguese brand, great Seiko movement, 200m plus water resistant ( in this case:300m ) good specs and Tritium tubes for a great lume experience were what made me take the plunge and Iīm happy I did! :)
    Great job on the Jellyfish and I also love the Ocean Diver GMT, lovely watch that is! :)
