Since 1993, the Seamaster Professional Diver 300M has enjoyed a legendary following. Today’s modern collection has embraced that famous ocean heritage and updated it with OMEGA’s best innovation and design.This 42 mm model is crafted from stainless steel and includes a blue ceramic bezel with a white enamel diving scale. The dial is sun-brushed PVD chrome colour ceramic and features laser-engraved waves and a date window at 6 o’clock.
The skeleton hands and raised indexes are blued and are filled with white Super-LumiNova, while the helium escape valve has been given a conical design.
The watch is presented on a stainless steel bracelet and is driven by the OMEGA Master Chronometer Calibre 8800, which can be seen through the sapphire-crystal on the wave-edged caseback.
Features
Anti-magnetic: The movement is unaffected by exposure to strong magnetic fields, even those greater than 1.5 tesla (15,000 gauss).
Chronometer: Label given to a watch which has undergone precision tests and received a certificate from an official body (COSC).
Date: The day of the month, displayed in a window on a watch dial at the 3 or 6 o’clock position, or within a subdial at 9 o'clock.
Helium escape valve: Decompression system which allows helium to escape from inside the watch when the watch is worn for professional use in pressure chambers. (Long-term underwater work, crude oil exploration, etc.)
Master Chronometer Certified: Guaranteeing the Swiss industry’s highest standard of precision, performance and magnetic-resistance, as set by the Swiss Federal Institute of Metrology (METAS).
Screw-in crown: Self-locking crown, screwed into the tube of the case, used for highly water resistant divers' watches.
Transparent caseback: A transparent caseback - frequently made of sapphire - makes it possible to see the movement inside the watch.
Unidirectional rotating bezel: A bezel which turns in only one direction. Particularly useful for divers who cannot accidentally rotate it in the wrong direction, which could cause them to miscalculate their dive times. A rotating bezel makes it easy to measure elapsed time.

Absolutely Love!
Size: 40D, Color: Warm Beige
I lost some weight and wanted a new bra. I love a minimizer. I randomly bought this and thought I'd try it. Seriously...I absolutely love it. I was a bra merchandiser for a VERY large company for years, so I have bought and tried on hundreds of bras. This bra holds, gives amazing shape and is so comfy. The straps are wide so they won't fall down. The band is tight but comfy. The wite doesn't poke. The fabric is soft and stretchy. The unlined cups lift and give you great shape. If you are thinking about it, do it. You won't be sorry!

Comfortable and supportive. Didn't last as long as some of the other colors.
Super comfortable and supportive. Color and design were cute. Only issue is the wire broke through after a few months. Have bought many others from this same seller and had better luck with how long they lasted. I would buy again because of comfort if it goes on sale. Green and light blue one were also comfortable but long lasting. Nude colored one digs in under bust and doesn't have as much softness around wires.

Wire pops out! Great shape and comfort
Size: 34D, Color: Oatmeal Heather
They last a couple months, but I wear these about once a week. The wire pops out enough (I have 4-5 of these), that I always carry a back up bra. The wire hurts and breaks skin, and moleskin doesn’t fix it. The minimizing and support is pretty good and the bra is comfortable, it just doesn’t last very long which is a shame. I will still buy them because it is a great fit, but I wish they reinforced the wire closing. I have a small band and large cup and it looks pretty good under tighter Tshirts.

Very happy with the way this bra fits, feels, and looks!
Size: 38C, Color: Sargasso
38C size
I am really happy with this bra. It has good coverage. Nothing spills out. It is two layers of fabric but no padding and no foam lining, so it does prevent some show-through but doesn't add bulk or size. It is slightly minimizing--maybe 1/2 inch off my bust, but doesn't smash me flat. It keeps good separation and support. The shoulder straps also stay in place! I get so tired of putting straps back on my shoulders that slide off over and over. The color is gorgeous. I may order more. I want to see how this holds up after washing and wearing several times, but it's beautiful and so far, I love it!

I’m freaking out DONT BUY THIS BRA
Size: 44F, Color: Cameo Heather, Size: 44F, Color: Cameo Heather
Back story- I ordered this bra like 4 times in 3 different sizes because I loved the look/feel of it but didn’t know my size after having my son & nursing. I returned 2 because they didn’t fit, then I got this size and was SURE it was going to be the right size, I opened the package & threw it on, realized the underwire had broken through the fabric and was so upset because I finally found the right size & it was broken GAHHHH. When looking at the underwire I noticed it looked a little worn in that area. The fabric looked like it was balling up. (during this time I was wearing the bra)
I took it off to examine it further and realized I WAS SENT A VERY USED, BROKEN IN BRA. While gagging and realizing I had just put someone else’s boob juice all over me, I noticed just how bad the wearing was on it actually was. I am disgusted, literally gagging over putting on a random persons sweaty, dirty bra that most likely had boob sweat and god only knows what else. Do not purchase from them, clearly they have issues with the underwire breaking through & sending someone a VERY USED BRA? come on…. I’m mortified
