Seiko Prospex PADI: What’s the Difference
Seiko has been around for decades, originating in 1881 as a Japanese watch manufacturer. Over the years Seiko has attracted a cult like following to the brand, and rightfully so as Seiko is seen as a budget friendly watch brand that is well respected among watch enthusiasts. Within the Seiko brand there isn’t a more iconic lineup than the Prospex watch lineup. This lineup dates all the way back to it’s inception in 1965 with the original 150M divers watch, a testament of Japanese reliability and an answer to the needs of the time. Throughout the years Seiko has innovated to support the functional requirements of divers, creating pieces such as the 600m WR watch, the 1000m WR watch, computerized dive watches, quartz dive watches, thermometer/depth gage watches, and many more innovative pieces.
Among the various innovations, Seiko has built the Prospex lineup as the backbone of their brand and centered themselves around the world of diving. In order to solidify this link Seiko would pair with PADI (Professional Association of Diving Instructors) in 2016, creating various special edition watches with the PADI insignia on them. While PADI has no history of watchmaking they are formally the single largest diver training organization, with over 6,300 dive centers and nearly 136,000 trained PADI professionals worldwide. This syndicate would prove to be a perfect fit between reputations that both PADI and Seiko had collectively built in the world of diving.
What Makes it a PADI Watch?
In actuality there is not much that differentiates a PADI watch from a standard Seiko Prospex watch in regards to the movement or specifications of the watch. Rather, a PADI edition watch features aesthetic differences in the color schemes used and insignia around the watch. All PADI watches are of course branded with the PADI stamp, positioned just south of center, taking the place of the Prospex symbol seen on standard offerings in the lineup. In order to maintain continuity, the Prospex symbol is moved just below the “Seiko” insignia on a PADI watches. The other piece of inscription that is unique on a PADI watch is on the case back, an engraving stating “Special Edition” which contours the case back medallion.
In conjunction with the difference in inscription, majority of the PADI pieces will have slightly different aesthetic details such as a different dial textures and finishes or different color schemes when compared to the standard Prospex watch. Majority of the PADI watches feature a red and blue dial scheme similar to that used within the Professional Association of Diving Instructors logo. However, that is not always the case you will see with a few examples in the current lineup.
To give you a point of reference, below is a comparison of a standard offering from Seiko to it’s PADI variant; below are the SRPE27 versus the SRPD27. Both of these pieces are similarly a Seiko Monster, however one is a PADI edition and the other is not. As can be seen in the image below, aesthetically the watches are very similar and you would be correct in assuming that because the specifications on the watch are identical. The main distinction with the PADI edition is the iconic “PADI” insignia south of center, the “Special Edition” on the case-back, an d of course the red and blue color scheme synonymous with PADI’s logo colors.
Aside from these main differences it has been said that the quality on a PADI piece is slightly better, with a few people reporting no hand to indices misalignment as Seiko’s are typically known for. However, this is just speculation.
Aside form their aesthetic differences with the color scheme, hand colors, and dial insignia, the two pieces are nearly identical in respect to design and internal specifications. Below are the technical specifications for comparison of the two pieces above:

As you have seen above, the uniqueness typically comes in the form of differing color schemes, PADI insignia on the dial, and the special edition marked case back.
