·Hello all members,![Smile :) :)](/styles/default/xenforo/smilies/smile.png)
My personal favorite hour-markers for both constellation and seamaster model need to be the arrowhead markers.
Today I would like to share my new incoming, the omega seamaster with triple case references (2657-2494-2521).
The omega reference 2567-2494-2521 comes with the unusual larger case than usual, approximately 36.5mm excluding the crown and 39.4 mm including the crown (usual seamasrer will be 34.5mm excluding the crown).
It was the gold cap case with the very uncommon “arrowhead markers”. Thanks so much @Tony C. who told me that some serious collectors would call theses markers other than the 3, 6, 9, 12 would be considered "shark's tooth", rather than arrowhead markers.![Thumbs Up :thumbsup: :thumbsup:](/styles/default/xenforo/smilies/thumbsup.png)
The serial number was 14,769,xxx using caliber 354 (17 jewels). This “chronometer” rated will show “adjusted five (5) positions and temperatures" legend engraved on the rotor. Please refer the movement picture below.
In my opinion, the dial was original waffle dial.
The arrowhead markers (plus some of the shark's tooth) were original.
The clover leaf crown might be the modern replacement crown because it is not “flat-footed.” I will change it to the correct model later.
The Caliber 354 movement with chronometer rated looks correct and quite clean.
The hands were correct and original too. The case was some polished.

It should be noted that it will look like the “two-tone dial” when you view from the certain angle.![Smile :) :)](/styles/default/xenforo/smilies/smile.png)

My research found only 3 examples of seamaster with the same dial pattern (non-date seamaster with the arrowhead markers).

I found watch no.2 and 3 from Facebook, unfortunately I don’t know the reference and movement number.
I will focus on the watch no.1 using the same font appearance.
https://watchesoflancashire.com/product/1954-omega-seamaster-2521-11sc-jumbo/
Bear in mind that this one is the jumbo version with the triple case reference too, though the rotor bridge was swapped at some point.
At first glance, I believe that the crosshair line should be thicker when it touches the 3/6/9/12 hour-markers (as watch no.2 and no.3), as we usually found in the constellation model. The red arrow pointed what I mentioned above. By the way, watch no.1 also looks alike.

I really appreciate the advice from Omegaforums’ members whom I asked via PM. It was very helpful !!![Psy ::psy:: ::psy::](/styles/omegaforums/psy.gif)
So sorry if I didn’t include your watch into my research, please share your example(s).
Thanks you for your valuable feedback, comments and like.![Smile :) :)](/styles/default/xenforo/smilies/smile.png)
I leave the question “can my watch be only one example in the omega seamaster jumbo chronometre, waffle dial with the arrowhead markers, which I believe it’s not easy to find?”
