Seiko Prospex Alpinist SPB503
Inspired by Seiko’s first sports watch from 1959, this new Prospex Alpinist model blends enduring mountaineering heritage with modern watchmaking technology. The archival teal-turquoise dial recalls tones found in early Seiko field watches, while signature Arabic numerals, wedge-shaped indices, and stylized LumiBrite hands deliver both clarity and vintage presence.
Designed for exploration, the watch features a rotating inner compass bezel, a magnified date window, and the classic Alpinist logo displayed prominently on the dial. The stainless steel case and bracelet are reinforced with a super-hard coating for enhanced durability, complemented by a sapphire crystal with inner anti-reflective coating for optimal visibility in harsh environments.
Equipped with the modern Caliber 6R55 automatic movement, this Alpinist offers a 72-hour power reserve, manual winding capability, a screwdown crown, and 200-meter water resistance. A transparent screwdown caseback reveals the movement and displays the iconic Alpinist mountain emblem, while the tri-fold push-button clasp ensures secure comfort on the wrist.

What Our Clients Say About Us
Mike and his team did a wonderful job making our dream come true!! Very fast and excellent quality!
Such a wonderful experience. It was my husband and my 16 year wedding anniversary on the day we walked into the store. We weren’t expecting to find a beautiful band with my taste and in our budget. However, the owner and his son Sterling were very helpful and patient. Sterling has excellent taste and such a calm demeanor. We really felt comfortable and the owner gave us a great deal for our anniversary I will never forget this experience. They even fixed my engagement ring by replacing a stone that had originally fallen out and they also tightened all the prongs because the main diamond was wobbling in danger of coming loose. They did this all same day within a couple hours while I looked for my anniversary band! This meant so much to me because I hadn’t been able to wear my engagement ring for many years and I thought it would be super expensive to fix. The last time I went to a fast fix place and paid close to $1,500. They did a terrible job and replacing one of the small diamonds that had fallen out with a dark dirty dark diamond that didn’t match the rest of the diamonds on the band of my engagement ring…After that I was so disappointed and discouraged to take my ring again somewhere to fix it. But Dejuan’s totally took care of me and I paid under $200 to replace the small dirty diamond and fix the damage the fax fix place caused. To walk out on my 16 year wedding anniversary finally able to wear my engagement ring after so many years of keeping it in the drawer… ugh I can’t tell you how sooo thankful I am for good honest people and professionals! Highly recommend and we will forever now be lifelong customers! Enjoyed the conversation and real genuine connection from both! Rebecca and David Samudio
Communication with Dejuan Jewelers was prompt and accurate. They gave me the date that they were going to recieve the watch which was promptly shipped the same day. Texted me with the tracking number and answered my question/ queries promptly. Very pleasant and professional. Highly recommend them to anyone looking to buy a watch. It was a pleasure to do business with them and I hope to be a repeat customer. Thank you!
Nice people, good service. They fixed my silver necklace for a fair price and did great work
