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 also polished blue ceramic and features laser-engraved waves and a date window at 6 o’clock. The skeleton hands and raised indexes are rhodium-plated 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.

    OMG!! I just picked up my ring and it’s absolutely beautiful! After 30 years of marriage my ring not only looks new again, but the center diamond and switching the prongs from 6 to 4 was the best decision! I will absolutely be returning to Azzi jewelry in the future! The photos don’t do this ring Justice… it’s 10x better in person! Brooke was such a joy to work with and made my experience an incredible one!

    This is an excellent ring and fine jewelery shop in Lansing. Having just purchased my new wedding ring, I can say with confidence that they have the one of the best, widest, and most inclusive men's wedding ring selections I've seen in Michigan. I was looking specifically for non-traditional metals for my ring, and sure enough I'm now the proud owner of a gorgeous Tantalum & Gold ring. I'll included a picture. I recommend dropping in before making a decision elsewhere, these guys are great. Special thanks to Elon, wonderful knowledge and a pleasure to work with!

Appraisal for re-purpose . Size 6 . Special consideration for a disabled USMC Vet is much appreciated 💚, thank you. Keep up the great work 😁

    Robyn at Azzi Jewelers is absolutely amazing! She was so welcoming and incredibly helpful with any and all questions we had. Her knowledge and kindness made the experience so enjoyable. If you’re looking for beautiful jewelry and exceptional service, this is the place to go! Plus, their boutique carries Shinola, which is such a great addition. Highly recommend
