Fantastic piece - my new favourite

I am extremely pleased with my new Borealis Estorile 300. I have the one with the yellow and black bezel. This is now one of my favourite pieces in my collection (and that is praise indeed).
This is my first experience of a ‘true’ gmt and am getting along with it quite nicely. The appearance of the watch is great and the lume is something else! It easily lasts until morning.
I have no problems with recommending this watch to anyone

Thank you

Almost perfect

I have the Black dial with the Black and Red bezel, and as I said in the title it is almost the perfect gmt. The only two improvements I would make is to reduce the water resistance to 200m and then take about 2mm from the height of the case dropping down to less than 13mm. This is just my wishlist you may be interested in something else, but it truly is a beautiful watch and very comfortable to wear. The watch also has great lume easily lasting through the night. The other thing about Borealis is the people and the way that you are looked after, and the customer service is second to none there was a problem with the first watch I received and I was given permission for my local watchmaker to look at the watch but he didn't think it repairable, and when I contacted Borealis a new watch was sent the next post, plus when I asked for a printed address label for returning the original watch I was informed that I could keep it for spares. That in my humble opinion cannot be surpassed, superb service.


The 50% deposit was marketing gimmicks

Borealis Estoril 300 GMT feedback

I am absolutely thrilled to own this watch! As a collector I own quite a few watches, but this Borealis Estoril 300 GMT is definitely one of my favorites. 😃👍


I have a few Borealis watches, but this might now be my favourite. The new on the fly clasp is sleek, well finished and works great. I love the white handset, yellow gmt and matte dial, very legible. This watch is a perfect size for my 7” wrist, wears even better than my Sintra, although this is a thicker watch. Lume is amazing, just feels at home on the wrist. Movement running less than +1 after couple days wear.
