The Subtle Differences Within the 15400 Lineage
My OCD kicked in last while I was looking at my 15400 I bought last month and began researching the 15400 myself.
I tried searching through the forums and couldn't seem to locate a thread referencing the subtle differences and changes even within the 15400 lineage. Thought I would share and see what you guys think. If you guys have more to add, let me know as well. Cheers. ![]() *Apologise in advance as these are not my images or pictures, but these seem to highlight the watches and subtleties quite well. As well, nor do I own two 15400 side by side to compare. From my research the blend of changes appears late H Series and I Series. Final changes are complete in the I Series in 2015. I'm not an expert by any means and the subtle changes may be around this date rate (give or take). Mine is a 2015 I Series and seems to incorporate all the new changes. Sold in July 2015.

Are you sure those are both 15400 pictures? The second picture might be a 15450 - you can see the 3 hour marker is significntly shorter in comparison.

Woops, pardon my filtering of pictures in my search. Here is the proper comparison of the dials and logos. *Appears I can't edit my original post, but here it is: ![]() (Not as great pic as the seconds hand is blocking). ![]() |

Thanks for this post! It was incredibly useful when doing my research on the 15400st RO.
Seems like the "older" model of the RO with the thinner AP logo on the dial is unique to this batch of RO. Produced from 2012 to 2015 - about 4 years of production because they standardized it to the "fatter" logo. Might be wrong but I don't think any other RO has that distinctively "thinner" AP logo on the dial other than this batch of 15400st. Really interesting! |

This is weird. I’m about to buy a 15400 H series but it doesnt have screws on the clasp. Any ideas why? It is a 2013 model.
