Good practice / care for my new IWC

Hi All,

I am new here, and so sorry to ask these basic questions that have probably been asked a dozen times. I did look for a search tool to look up previous posts, but this forum does not appear to have one.

I bought a Portofino Laureus and I love it!

I would like to know the following;
1. It appears to have approx 40 hours of operation when not wearing it. Is that about right? Is there a point of winding the watch that it can damage the mechanism? or does it have a release that would prevent this concern?
2. If the chrono has been used and stopped, and not reset, is the mechanism under pressure? that is, is their any harm in not resetting the chrono back to zero?
3. If i use the watch as a daily wear (which i am very much inclined to do), and therefore take the watch off possibly several times per day, how long will the latch last on the milanese bracelet? Is it covered under warranty? if so, for how long? if outside of warranty, what would this cost to replace?

Congratulations on your new Portofino and your support of the cause it supports.

A few answers:

There is a forum search function. See the "magnifying glass icon" in upper-right of the screen. You can type a phrase or word like "over winding".

There is a clutch that will protect the movement from over winding. This is a basic feature of automatic watches.

Not sure what your 2nd question is asking. If your watch's power reserve runs down and stops while the chrono was running? There's no issue with that. I believe when you wind up the watch, the chrono should start up with the movement, since it's engaged. Noting to worry about.

IWC bracelets are very robust - and represent some of the finest and most durable in the industry. They are pricey and worth every penny. Will last decades.

I believe the answer to your second question is "no". You need not feel compelled to reset the chrono second hand; or, more likely what you are asking-it's okay to forget that you did not reset to zero.

Hi HYJUKI87 - Welcome to the forum :-)

Congrats on a beautiful piece. I considered a Porto Chrono a few years ago, but finaly got something else.

To answer your query in a bit more detail-
1. The 40 hrs you have experienced is great. Your mvt is specified to have 46 hours reserve. To get this, you will need to build up full power at the beginning. It is recommended to wind plus/minus 30 turns of the crown at first wearing or after resting for some time.

1. As PADJ has said, Once chrono is stopped, it is completely disengaged from the mvt and is not under pressure. No problem leaving it where you have stopped it. I do it all the time. I set my chrono to the expiry time of parking meters, so I don't forget.

2. Excellently answered by ARDOIS.

Hi All,

Thank you very much for your responses, and for setting my mind at ease.

Congratulations on your excellent choice of new watch. Welcome to the forum too. Do you know how to share photos. We like photos here.
