Hi everyone
Could you help me to check this Longines Ultra-chron is a legit one or not
It use the caliber 431 with Jumbo size 37mm
Thank you so much in advance

 

I'd be suspicious of the dial. It maybe the way the photo is taken, but minute markers 6-12 not clear, ultra chron text looks heavy (not crisp) and horizontal crosshair looks uneven.
It may be ok, hard to tell. Would be one I'd want to view in person, perhaps with a loupe to be sure.

 

I rather think it’s fine but I agree with @ken_hodson that the photos aren’t particularly helpful.

The movement looks fine to me and the dial is probably okay but the caseback doesn’t have the Ultra Chron logo.

I did have a look on Chrono24 and saw a couple with a similar caseback so, I suggest you do a bit more comparing.

You don’t tell the price or location but it is definitely down to you.

 

I think the dial is OK, but the case is unattractively soft for me.

 

Thank you su much for your response
I won this watch from local bidding group in Vietnam. Its just 200$
FYI, price in VN quite lower than other countries but 200$ for this Longines is still good for me. The Ultra chron should be around 250-300$

 

I just won from bidding and the watch is on the way shipping to me. Later when I recieve it, I will try to take a clearer picture
Thank you so much

 

I think that’s an excellent price, no, a bargain, for a nice Ultra Chron.

I hope it lives up to expectations and look forward to seeing more photos

 

Hi @Spruce
Hi @ken_hodson
I attached here some pictures
Please help me to check
Thank you so much

 

Lovely

 

@tancromatit These are better pictures. The dial has some degradation (or 'patina', as they say). Different lighting conditions probably makes this more or less obvious - the first photo of the three that you have posted looks nice. There is some loss of the edge of the minute markers around 9-10 o'clock...not a major deal. Scrutinising photos and zooming in does tend to bring out the worst. It'll look good on the wrist, I'm sure .

For the price, I'd say it's a good buy.

I have a slightly different version. They are a really great series of watches and interesting from a 36,000bpm movement perspective too.

 

Thank you guys so much
I have another question
I heard that a 36000 beat watch would need more service than other watchs. How do you think about the cal 431? Is it need service/lubricant annually?

 

Longines have always made quality watches and, as far as I know, all watches should be good for running, regardless of whether they’re hi-beat or not.

The only problem I’ve found with 60s/70s Longines (like yours) is sourcing replacement parts if and when they’re needed.

 

Hi Spruce
Thank you for your information
Just hope mine will run for long
Have a nice day to all of you

 

My understanding (admittedly very basic!) Is that to maintain 36,000bpm the mainspring is under some additional tension, which in turn puts the gear train under extra force/tension, potentially meaning the components may wear out quicker...despite this I think its OK for normal service intervals.

Happy to be corrected by anyone more knowledgeable!

 

Do you need to lubricate watch every year/2 year or just use it until it have huge interval in week/month?

 

Nah. Just get it serviced when it arrives and maybe see what your watchmaker thinks with regards to future servicing, but yearly or even 2 yearly is likely to be overkill.
