I bought this Seiko Cocktail Time and thought it would be nice to do a blog post on it and its predecessor, the SARB065.

The Cocktail Time models were first introduced in the Japan domestic market and came with the 6R15 movement. They were offered under the Mechanical line with the most popular model being the SARB065. The 6R Cocktail Time models were however discontinued and new 4R based models were announced during Basel World 2017. These 4R Cocktail Time models have a similar design as their 6R predecessors but are powered by the 4R35 and 4R57 movements. They are no longer JDM models and are sold worldwide under the Presage line.

This particular variant that I bought is the SRPB47J. It is made in Japan and distributed here in Singapore by the official distributor, Thong Sia Co. Interesting, the press release on Seiko’s global website did not include this model.

https://www.seikowatches.com/press_release/2017/RLS1703-08/index.html

Here are the eight variants mentioned in the press release. The four models in the top row are based on 4R57 movement and the other four in the bottom row are based on 4R35 movement.

Here’s the stock photo of the SRPB47J.

I chose this particular variant as I prefer the combination of rose gold hands and indices and the off white dial. It is easy to read the time as the colour of the hands and indices stand out better on the textured dial. It also has a nice vintage feel to it.

This watch has a diameter of 40.5mm which is just nice for me. I have installed a light brown leather strap to match the rose gold hands and indices. The lug width of this watch is 20mm.

I observed the following differences when comparing the dial with the SARB065:

• The “SEIKO” word on the 4R model is bigger.

• The little 3 O’Clock marker beside the date window is different. The 6R model has a rectangular shaped marker whereas the 4R model mirrors the 9 O’Clock markers with part of it “eaten” by the date window.

• The 4R model has the word “Presage”.

I already have several Seiko’s with the 4R35 movement. However, the 4R35 movement in this watch comes with a gold rotor which is something different from most 4R based models. This is my first Seiko with a gold rotor.

Below, I show you the caseback of the SRPB47J with gold rotor together with that of another 4R based watch with a standard stainless steel rotor, and lastly, the caseback of the SARB065.

I also notice that the 4R version of Cocktail Time is a slightly thinner watch. In the pictures below, the watch on the right is the 4R version. You can see that the side of the case is thinner on the 4R. I estimate the 4R model is about 0.5mm thinner from front to back.

The crown is obviously different on the 4R and 6R model. Not only they are different in shape, the ‘S’ engraving is also different.

Here is the metal bracelet that came with the watch. It has folded end links which is not an issue to me as I am not a bracelet user.

This is an international Presage model available at all authorized Seiko retailers. My watch came with instruction manual and warranty booklet and card from Thong Sia.

Conclusion

The 6R Cocktail Time has a better movement with longer power reserve and higher accuracy specs. The 4R model has a different crown and gold rotor and is slightly thinner. I chose the 4R model only because it has the colour variant that I prefer.
