Prospex Speedtimer Mechanical Chronograph. Designed for those who treat life as the ultimate adventure, the Seiko Prospex line meets every challenge with technological excellence and style. Celebrating Seiko's first precision chronographs, developed for international sporting competitions in 1964, as well as its 1969 introduction of the world's first automatic chronograph, this exceptional watch provides chronograph measurement of up to 30 minutes of elapsed time in 1/8-second increments. The 34-jewel automatic movement, visible through the screwdown see-through caseback, beats at a frequency of 28,800 vibrations per hour, with a power reserve of approximately 45 hours and manual winding capability. The proprietary 8R46 movement includes a column wheel and vertical clutch mechanism allowing for smooth, stutter-free movement of the chronograph hand while providing longer wear and efficiency, and maintaining the power reserve better during chronograph operation. Crafted of stainless steel with super-hard coating and tri-fold push button release clasp, this extraordinary timepiece also features a vibrant blue dial with LumiBrite hands and markers topped by a dual curved anti-reflective sapphire crystal and is paired with a sleek black crocodile strap. 10 bar, 100M Water Resistant

I recently purchased an Omega timepiece from Craig, and my experience was exceptional from start to finish. Customer service was top-notch; I had a few questions regarding warranties and shipping options, and Craig was responsive and knowledgeable. Craig takes his time in ensuring customer satisfaction! He also ensured I walked out with an amazing deal that no other Jewelers were willing to do. The quality of the watch exceeded my expectations, and I am thrilled with my purchase. Overall, I highly recommend Martin Jewelers for anyone looking to buy a watch. Their commitment to quality and customer service truly sets them apart. I will definitely be shopping here again in the future!

Brought my wife's diamond watch to Martin Jewelers to have it serviced. The watch was finished ahead of schedule, the repair was successful, and it was apparent to me that they had also taken the time to clean the watch very well, bringing back its brilliant luster. I like that there is a separate service area. The folks I interacted with were very polite. The store is beautiful and clean with gleaming display cases and plenty of room to walk around and shop. This was my first visit to Martin Jewelers and I will be back for any of my future needs. Abundant pay parking behind the shop and the rear entrance are accessible to the public.

Top notch service, excellent selections and quality jewelry. I’ve purchased gifts for my wife and daughters over the last ten years and I always have a great experience at Martins. Anyone there was the slightest issue with a piece, they stood behind their product. Jeff is great to work with. I’ll tell him the occasion, set a budget and he always delivers above and beyond. There is a reason why they have 2k five star reviews…..
