Omega Seamaster Planet Ocean 600M Titanium Blue Men’s Watch 232.90.46.21.03.001

A Well Designed & Executed Quality No Non-Sense Diver’s Watch
13 C05 Omega Planet Ocean ReviewPlease verify you are interested in or buying the Omega with the 8500 (85XX) calibre.Two months ago I received the Ω Planet Ocean (PO) with Omega’s 8500 calibre/ movement (internal mechanism of the watch). I note the movement because Omega sells a nearly identical watch with the 2500 calibre which I am NOT reviewing. Based on other owner’s comments the 8500 represents a significant improvement over the 2500.The Ω PO watch replaced an Omega Speedmaster Day Date I owned & I harshly but accurately reviewed. The PO represent everything the Speed Master did not. The 8500 calibre PO is sturdy, durable, easy to read, well designed, & innovative.External ComponentsThere are several sizes of 85XX calibre watch cases ranging from 37.5 mm to 43.5 mm & some have additional features. Regardless of the specific model each is thick & heavier than watches of comparable diameters.The fit & finish of the face, hands, hour marks, band & case are flawless & impressive.The watch links are solid & each link can be removed with an appropriately sized & sturdy screwdriver. Note, be very careful removing the screws because they are small & easy to lose.The clasp contains the Diver’s Extension mechanism for temporarily expanding the band to fit over a wet suit; remember this is a professional diver’s watch. I periodically use the expansion feature to wear the watch on the outside of a sweatshirt sleeve (so I can see the time when running or bike riding). However, because of the Diver’s Extension, there are no holes on the side of the claps for watch spring bars/ pins to fit negating any fine length adjustment there. To compensate the watch band contains, near the clap, a half sized (or so) link that can be removed to improve fit.The watch uses a crystal that minimizes reflection from light sources making reading the dial extremely easy. The ability of the crystal to diffuse light is amazing, I find the chrome trim around the hour marks & hands reflect more light.A crystal on the back of the case allows one to see part of the internal mechanism of the watch. However because of the housing for the calibre, there is not much to see other than the rotating/ spinning balance wheel.The black dial with the contrasting chrome/white marks, hands, & date makes reading the time effortless.The hour marks & the hour & second hands use a turquoise colored luminescence. The the minute hand & dot @ the 0/ 60 minute mark on the uni-directional bezel uses a green colored luminescence to distinguish it from the others.The Omega team designed the arrows @ the end of all three hands so they do not completely overlap each other. Although not much of an issue during the day, the feature is welcomed during dives or in darkness.If one tires of the color of metal insert in the bezel it can be swapped out @ considerable cost & effort. I found genuine Omega bezel inserts on eBay @ over $250.The bezel rotates in one direction as a safety feature for divers using the bezel to note dive time.Internal ComponentsTo learn of the impressive quality of the 8500 movement/ mechanism this video can better demonstrate it than my mere words. Cut & paste this link http://youtu.be/yDULLlGLn6s or search for “Omega planet ocean manual 8500” in Youtube.Operating “Instructions”The owner’s manual represent the only bad (really terrible) part of purchasing the watch. The Omega executives & managers should feel shame & embarrassment for creating possibly the worst set of instructions for a watch. A massive 424 page Operating Instruction (owner’s manual) accompanies the watch. However, you need not fear the thickness. Only 43 pages contain instructions written in English. Of the 43 pages, 14 pp cover the table of contents & warranty information. So 29 pages covers the instruction for this watch and 65 other models. SIXTY SIX (66) models are covered in 29 pages of instructions!!!To use the manual you must first identify the “Calibre” number of the watch. The calibre number appears on a red plastic card found inside a pouch inside a compartment, inside the red leather box in which the watch arrived. After identifying the calibre flip through the entire Operating Instructions (the part written in English) looking for the Calibre Number to find which specific instruction applies. The video, link above, provides much better & thorough instruction for the 8500 Ω PO.SpecificationsOmega states the watch’s water resistance is 60 bar (600 metres / 2000 feet), far more water resistance than most people, even recreational divers need.From the Omega Website: Chronometer, Date, Helium escape valve, Screw-in crown, Transparent case back, Unidirectional rotating bezel, Crystal Domed scratch-resistant sapphire crystal with anti-reflective treatment on both sides, Steel case. Caliber Omega 8500: Self-winding movement with Co-Axial Escapement for greater precision, stability and durability.

Power reserve: 60 hoursI hope this review helps.15 C08Two years later as my daily wear watch, including one year in the harsh environment of a Navy ship, I experienced no problems. What I wrote before remains the same.
