PROSPEX SPEEDTIMER MECHANICAL CHRONOGRAPH SRQ037

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 charcoal gray dial with beige LumiBrite hands and markers topped by a dual curved anti-reflective sapphire crystal. 10 bar, 100M Water Resistant

    I was in search of a family owned jewelry store on a Sunday & discovered Dejuan Jewelers in Woodland Hills. I noticed a missing diamond in my Mother's ring which I have been wearing since 2000. The ring contained 5 diamonds, one for each of my siblings so it was absolutely precious to me. Both Michael and Sterling listened to my story, assuring me it would be expertly repaired with a matching diamond, beautifully cleaned and ready for pick up end of the week. It was ready 2 days early and was astonished at its polished, gorgeous condition! I was thrilled knowing I made the right decision to trust these two gentlemen Jewelers, both professional, extremely knowledgeable and kind. It was a pleasure working with them, and learning about their passion for this exquisite craft! Robyn Bensinger 10/7/2025
