Thank You, Jay

Not that you need any encouragement, the 5980 seems to have a love/hate following. Nevertheless from reviewing posts it seems to have proven its reliability and I will share my daily wearer experience since delivery in April 2008 (it's been on my wrist 350+ days).
1. Easy to wear and no worries about wet weather
2. The weight is balanced with slight heft and very comfortable on my wrist
3. Wears visually smaller than specs since dial is 28 mm even thought case is 44mm including wings
4. No problems for me with 12.5 mm thickness since it sits well on my wrist
5. I like the aesthetics of dial and virtually every woman in my life finds watch attractive and no "dated" comments
6. I feel that the bulls-eye chrono counter overcomes any non-contemporary styling
7. Versatile watch that can be worn casually in jeans or shorts or dressy in a suit
8. Even though I use the chrono feature often it is not always early to read when minute hand covers the counters
9. Back end of chrono minute counter covers the chrono hour counter which is the same length--suggestion to fix would be either to use different colors for these hands like 5960 or eliminate/shorten back end of chrono hands
10. Feel of chrono pushers is nice and wings provide an unexpected ergonomic feature since perfect resting places for your thumb or index finger when pressing pushers
11. Scratches easily but I don't expect a watch in constant use to be pristine
12. Bracelet is supple for all metal and similar to my impression of first RO that I held
13. Bracelet double deployant clap is fairly secure and even when I failed to close the locking clasp the watch has never fallen off my wrist
14. Prefer 5980 to 5712 because I'm not seduced by the latter's aesthetics (too similar to 5035/55/85) and their list prices are relatively close plus 5980 movement is unique in comparison
15. Did consider 5960 versus 5980 but for my lifestyle the Nautilus is a hands down winner
16. Marketing description of continuous moving seconds hand is somewhat misleading since really only accurate as chrono feature although one might use is as a pseudo time-related second hand
17. Accuracy is good to outstanding--my early tests were +/- one or two seconds a day but stopped tracking several months ago
18. Since the rotor and bridge word hides much of the movement a non-display case back would have been just fine
19. Finishing is acceptable although since marketed as dual purpose sports and dress watch perhaps portions that are sand blasted might have been upgraded?
20. Value and price; well that's all relative within the context for each individual isn't it
Bottom-line: the 5980 it is a robust and flexible watch that does what it is advertized to do--a keeper. Cheers and live well!
Hi JASNY, just now responding since took yesterday off from Internet to celebrate Decoration Day.
1. When minute or hour hand is between 22 to 38 after sometimes chrono timing can be difficult to read since hand may block counters but not the entire period. I use chrono for client consulting and time in casino but for practical purposes I'm able to make a good estimate when temporarily blocked.
2. I have several scratches on top of bezel but I suspect most are due to my carelessness. Bracelet has bruises on several links when I forgot to remove watch while unpacking and moving a heavy sculpture.
3. I agree with your comment about timing events whatever you want and I repeat that the wings provide nice ergonomics when pressing the pushers.
4. I previously owned 5165 but no dato, but I much prefer the look of this Nautilus to Aquanaut and inclusion of complication is great because I would be less bothered by case wear due to regular use of 5980 as opposed to care that I would want to afford a dato.
Regardless of your choice, or if you decide to acquire several watches for celebration, enjoy your 50th.
In May 2008 I brought this 5980 and I promised not to buy any watches for at least 2 years.
Mt wrist is less than 16cm. It still wears comfortably.
(But...later, I changed my promise to "not to buy any watches more expensive than 5980 for at least 2 years"
)
Jay,
If you will only use the chrono. occasionally, the watch is fine and beautifully made. If you will depend on it many times a day for billable hours, this is not the watch for you, as the chrono hours and minutes are too often unreadable. Sadly, Patek has never made any chrono. that is well-designed for this purpose.
I had a similar desire to own this watch, but gave it up because of the unreadability of the chrono. AP and VC make more profession-friendly chronos.

Jay,
Earlier in the thread you mention timing patient visits. Psychiatry or any branch of forensic medicine requires a 6-, 10-, or 12-hour totalizer for tasks ranging over 30 or 60 minutes, for which the worthy candidates are AP Royal Oak Chrono., Royal Oak Offshore, or VC Overseas. Any other specialty can probably use PP 5070, A. Lange Datograph, VC Malte Chrono, or AP Jules Audemar chrono. These choices are all great, but I can tell you after owning about 50 chronographs that just about anything else is a waste of money if you care about quality.
