It comes with several features that make it appealing to both professional divers and watch enthusiasts. In this article, we will discuss the pros and cons of the Seiko Prospex Divers SPB187J1 in detail, giving you a comprehensive overview of this timepiece.


  1. Excellent Build Quality: Seiko is known for its exceptional build quality, and the Prospex Divers SPB187J1 is no exception. The watch is robust and durable, capable of withstanding the rigors of professional diving. The case, bezel, and bracelet are made of high-quality stainless steel, ensuring long-lasting durability.
  2. ISO 6425 Certification: The SPB187J1 is ISO 6425 certified, which means it meets the strict standards set for diver’s watches. It has undergone rigorous testing for water resistance, legibility, and functionality. This certification ensures that the watch is reliable and suitable for use during professional diving.
  3. Water Resistance: With a water resistance rating of 200 meters (660 feet), the SPB187J1 is more than capable of handling recreational and professional diving. The screw-down crown and case back provide an additional layer of protection against water intrusion.
  4. Automatic Movement: The watch is powered by Seiko’s automatic movement, known for its accuracy and reliability. The movement requires no battery and is powered solely by the movement of the wearer’s wrist, making it convenient and hassle-free.
  5. Luminous Indexes and Hands: The dial of the SPB187J1 features large, luminescent indexes and hands, ensuring excellent legibility even in low-light conditions. This makes it easy to read the time while diving or in any other low-light environment.
  6. Unidirectional Rotating Bezel: The SPB187J1 comes with a unidirectional rotating bezel, an essential feature for diver’s watches. The bezel allows divers to keep track of elapsed time while underwater, providing an added layer of safety during diving.
  7. Sapphire Crystal: The watch features a scratch-resistant sapphire crystal, which is highly resistant to scratches and damage. This ensures that the dial remains clear and legible, even after extended use in demanding environments.
  8. Date Window: The SPB187J1 includes a date window at the 3 o’clock position, displaying the current date. This feature is practical for everyday use and adds to the overall functionality of the watch.
  9. Comfortable Bracelet: The bracelet of the SPB187J1 is well-designed and comfortable to wear. It features a secure folding clasp with a dive extension, allowing for easy adjustment and ensuring a secure fit over a wetsuit.
  10. Versatile Design: The SPB187J1 has a versatile design that can be worn both underwater and in everyday situations. It is a versatile timepiece suitable for both casual and formal wear.


  1. Limited Availability: As with many Seiko models, the SPB187J1 may have limited availability in certain regions. Due to its popularity, it may be challenging to find one in stock, especially at authorized dealers.
  2. Size and Weight: The SPB187J1 is not a small watch, and some may find it too large or heavy for their preferences. The case measures 42.6mm in diameter and may not be suitable for those with smaller wrists.
  3. Price: The SPB187J1 is considered a mid-range diver’s watch, and its price may be a factor for some potential buyers. While it is reasonably priced considering its features and build quality, it may still be outside the budget of some individuals.
  4. Lack of Ceramic Bezel: Unlike some higher-end divers’ watches, the SPB187J1 does not feature a ceramic bezel insert. While the stainless steel bezel is still functional and durable, a ceramic option would have added a touch of luxury and scratch resistance.
  5. Non-Hacking Movement: The automatic movement of the SPB187J1 does not have a hacking feature. This means that the seconds hand cannot be stopped when setting the time, which can make it slightly less precise when synchronizing with other timekeeping devices.
  6. Limited Strap Options: While the stainless steel bracelet is well-made and comfortable, some users may prefer to use different straps or bands to customize their watch. However, the availability of aftermarket options may be limited due to the specific case design.


The Seiko Prospex Divers SPB187J1 is an excellent choice for those looking for a reliable and capable diving watch. Its build quality, ISO 6425 certification, and water resistance make it suitable for professional diving, while its design and functionality also make it a versatile timepiece for everyday wear. Although it has a few minor drawbacks such as limited availability and the absence of a hacking movement, the SPB187J1 offers impressive value for its price range. Overall, it is a highly recommended watch for divers and watch enthusiasts alike.
