Rolex

Never mind the watch, that is probably one of the best calculators made ...

I love the HP15C and actually own two of them as reverse Polish notation is so much better than an equals sign!


(I also have the app for my iPhone as well.)

Cheers,
Jonathan

A little bit of green to finish in beauty! ...  

Very nice! And iconic calculator captured in your picture!

Two timeless instruments. Once you get used to RPN you don’t use anything else!

Just for smiles and humor ... why are you not using graph paper ;-)

Ah that is a great question! for the type of book/paper I like to use (Clairefontaine from France because they have thick paper) I simply could not find graph paper locally! :-)))

Happy to see HP15C lovers here Jonathan! Such a joy to use. I also have the RPN app on my phone and iPad :-)

That is a very nice watch.

Green is a very attractive color for that Rolex!

Thanks and I agree it also goes well with blue. Feels weird to wear a green dial (my first one) but its easier to match then I thought

 
 By: Chronometer (aka yacomino) : August 18th, 2023-19:13

Iconic watch, yes.. Iconic calculator, not so much!

I think this is the sports equivalent of a Calatrava! The proportions crafted like a fine piece of marble. 👍

Great analogy! That said I would love to add a Calatrava to my collection!
