According to most legitimate online information available, the Seiko 7S26 and 7S36 movements made their debuts in 1996. The 7S26 movement was the backbone of the Seiko 5 range and many other models such as the Diver SKX007 and the SNK 7S26 range.

The upgraded 7S36B was introduced in 2006, and the 7S36C was the last variant that debuted worldwide in 2011 but 2010 models are known to be found in JDM models. The 7S26 and 7S36 were discontinued in 2018 in favour of the 4R3X range that had hacking features.

This is a May 1997 Seiko SKX781 Diver 7S26B-0350 23J Japan Made Discontinued "Orange Monster" Model that is highly sort-after due to its scarcity.

This watch has a stunning orange dial, 3D white baton lumen markers and hands ala sports design, and the dial lumen markers and hands work as though brand new. The unique shaped bezel is also located around the crystal as per typical diver watch.

Its 200m heavy duty silver case with built-in lugs was cleaned and buffed to reveal a fantastic finish albeit a few miniscule scratches that are barely noticeable to the naked eye. The crystal is original and is in excellent condition after a good buff albeit miniscule scratches still do exist.

The crown is located at the traditional 4H position and is nicely tucked away to prevent damage or snags. The day and hands quickset works by uncorking the crown to the first and second levels to adjust accordingly.

The Day is in English and Spanish, thus confirming its Made in Japan status! cool!

The movement INCLUDING THE MAIN SPRING was carefully stripped, meticulously cleaned, oiled, re-assembled, and calibrated on 21 October 2025. In short, it was given an overhaul and should be able to operate unhindered until the next servicing thereby giving the owner peace of mind.

Equipped with the classic 7S26 movement, it has 21 Jewels that operate at 21,600 BPH. The time-grapher, shows excellent readings of 0 seconds and amplitude of 138 with a straight centred line! Such readings are truly exceptional even by brand new modern automatic watch standards whereby the accepted tolerance is -20 to +40 seconds a day! This is a testament to the quality, excellent power reserve, the meticulous care provided over the years, and the painstaking expert calibration conducted.

The case width and height are approx. 42mm (w/o crown) and 47.5mm respectively. The lug width is 20mm; and the brand new NATO can accommodate wrists up to 210cm; hence, this watch is suitable for men and the modern women. A brand new Seiko Wave Diver Strap with silver buckle is also included as part of the deal.

To the best of our knowledge and expertise when overhauling the timepiece, the watch is 100% original Seiko components from this particular watch. No parts were replaced with aftermarket or modified parts.

Even though the seals and gaskets are in place, this timepiece has not been water-resistant tested due to its age.

The pictures provided shows the watch in stunning condition. The only drawback is the lack of documentation and original box. An aftermarket box or purposeful carrying case will be provided instead.

Bear in mind that this watch has seen many of the previous owners’ ups and downs in life, and should be cherished and preserved for the next generation to savour such engineering beauty.

This rare watch will make a beautiful birthday present for that special someone born in May 1997, and its value will appreciate over time.

This is a highly sort-after May 1997 Seiko SKX781 200m "Orange Monster" 7S26B-0350 Divers that is not easily available in Singapore; so, be unique and wear a Seiko watch that is almost impossible to source in such fine condition.
