I had been looking at replacing a Zenith in my collection and had been looking at the striking 10th and the 36,000. I personally find these watches interesting due to their technical achievements and they have a smart almost 'dress' watch look although obviously they aren't in the classic sense and my collection is mostly divers. Zenith have really come on in the last few years and if you've owned a more recent Zenith you will know their finish is stunning.
On viewing at my local AD I came across the El Primero 410. Chronograph, with compete calendar and moonphase, I love all the complications together and it reminded me of the Doublematic which I also love. The 410 is based on the same 410 from the seventies and shares the same looks although its slightly larger at 42mm. At 42mm it wears about as large as it can go without looking to large. Some people may find the dial busy but it works for me and there is a lot worse out there. The dial is still functional for me despite all the dials and the grey dial is quite elegant. The 410 comes as a limited edition of 500 although you don't often see Zeniths in the wild. The El Primero has a 50 hour power reserve which is more than sufficient and you have a nice case back to see the movement.
The only thing I do dislike at the moment is the clasp, its not easy to get close, but that might just be me. The strap is a very nice alligator leather with a rubber finish on the inside making it very comfortable.
