Accuracy of new Portuguese Chrono Ref 3714

As I previously posted, I purchased a new Portuguese Chrono last week which is great. However I've time tested it against an official clock, and in 5 days it has gained 25 seconds. That seems to be quite a lot? Does anyone know what the expected results for a brand new watch should be?

Original Post...

Five seconds a day is within spec. Enjoy your IWC and don't worry. If you want something more accurate, you may need a quartz watch. Five seconds per day is okay for a mechanical watch.

Thats what makes every mechanical watch having an personality!

Enjoy it!

First of all, congratulations on a great acquisition.

As Bill mentioned, 5 seconds is well and truly within tolerance. I've seen much worse. :) Besides, your watch is new, meaning the lubricant hasn't worked its way evenly around the components yet. Give it time (a month or two) to settle before passing final judgement.

In the mean while, go savour your new prize!

I just read on the forum that +/-0 + 7 sec per day is within the target for an IWC. I just checked mine out as well and it has gained 7 sec per day, measuring over 3 days. At first I was a bit disappointed to be honest, 7 sec per day and more or less not waterresistant. But to be honest, I am starting to enjoy My IWC Portuguese more and more. I love the way the people with the knowledge of watches gives thumbs up, and to all the other people it doesnt scream expensive, but for me it's a friend for life.

Take care of it and enjoy it, even if it gaines couple of sec per day.

Thanks! I definately will. It's nice to hear that +5 seconds is normal. It doesn't worry me at all - I just wanted to check that it wasn't faulty so that I can go on enjoying it without having to ship it off for repair!

Today I checked my Portuguese 7 day reserve and was surprised that it had gained 2 minutes over a period of roughly 30 days. Now reading your comment that it can go from 5 to 7" a day and multiplying this by 30, we reach 150", or a little bit over 2 minutes. Feel now more relieved :-). As Bill B. said: more accuracy get an quartz, BUT then it's not an IWC Portuguese!. Very little watches on the market beat the beauty and presence of an Portuguese.

Two days ago I was in Madeira for a golf tournament. Whilst waiting for my drink at the bar a fellow golfer came and stood by my side (also waiting for his drink).When he saw I was wearing my Portuguese, he said "what a lovely classical watch", and we proceeded into a very interesting conversation about watches. When we parted he gave a thumbs up for my IWC, which made me feel very proud to have one. Amazing how this particular model attracts so much attention. Well, it is beautiful!

Hello TS2342,

Congratulations on your Portuguese! One thing though, mechanical wristwatches don't like brutal shocks and in general it's better not to wear them playing golf.

Kind regards,

Clemens

.... When you still are not happy with to accuracy of your Portuguese Chrono,
I offer you na IWC-PD Chrongraph (Quartz meca quartz) as more accurate "Exchange" watch, with the same functionality :-o

As JL mentioned, settling in can make a big difference. In March I got a new watch made by a different company. At first it was gaining 5-6 sec/day. I knew that was within spec but was a little disappointed that it was right at the limit of acceptability for a COSC certified watch. After a couple of months however, it has settled in nicely to about 2 sec/day. One other thing, many watches will gain more time when the power reserve decreases. Keep your watch well-wound and you may see some improvement.

Hello Clemens,

NOOOOOO!, I had it on AFTER playing golf with my Swatch.
I know that mechanical wristwatches do not like to be brutally shocked.
Thanks for the tip!. For golf there is Tag Heuer's Golf special, designed for being bashed around, but for the price of this watch, I go on with Swatches !
