What movement powers the Bersigar Polaris 1790 Silver Black?
It runs on a Japanese 9020 automatic movement. It winds itself from the motion of your wrist, so there is no battery to replace.
Can I swim with the Bersigar Polaris 1790 Silver Black?
Yes for swimming. It is rated to 100m (10 ATM), which covers rain, hand-washing and pool or sea swimming. It is not intended for scuba diving, and avoid hot showers and saunas.
Will the Bersigar Polaris 1790 Silver Black fit my wrist?
The case measures 42mm — a mid-to-large size that suits average and larger wrists (roughly 16.5 cm / 6.5 in and up). Our watch size guide (/pages/watch-size-guide) explains how to measure your wrist.
What does the dial of the Bersigar Polaris 1790 Silver Black look like?
It has a matte obsidian black with small-seconds register dial, framed by a fixed black sapphire bezel, under an anti-reflective sapphire crystal.
Are there other versions of the Bersigar Polaris 1790?
Yes. Other versions we carry include the Bersigar Polaris 1790 Silver Green, the Bersigar Polaris 1790 Rose Gold Brown, the Bersigar Polaris 1790 Silver Blue. Availability changes with stock, so the collection page always shows what is in stock today.
Who is the Bersigar Polaris 1790 Silver Black for?
On the ChronoSeasons dial it sits at Hour VI — Field & Adventure, part of the Expedition season, and suits travel, the outdoors and long days on the move. It also appears in our Pilot & Aviation edit.
Is the Bersigar Polaris 1790 Silver Black authentic, and what warranty is included?
Yes. It ships brand-new and boxed from the brand's verified channel. Unworn watches can be returned within 30 days of delivery.
I am a machinist and usually skeptical of $220 watches sold online, but the brushing on this 316L case and the sapphire bezel are well executed. Note that the high-beat automatic rotor has a slight audible whir in a dead-quiet room.

Coming from a machinist, that compliment on the case brushing means a lot, Jacob! That unidirectional rotor sound is normal for the 9020 series.

Accurate 9020 automatic movement
Checked timekeeping over ten days and the Japanese 9020 automatic is averaging +4 seconds per day. Case tolerances around the fixed black sapphire bezel are tight, crown action is firm, and the matte black dial has zero glare.

Four seconds a day is right where we like to see that 9020 caliber running, Lawrence! Thanks for the review.

Sharp black dial for meetings
Wore this with a charcoal suit to a city council meeting and it looked right at home. Sits flat enough on my wrist to clear my shirt cuff, though the black alligator-grain leather strap was pretty stiff for the first 3-4 days.

Thanks for the feedback, T.! Glad it paired well with your suit, and that leather strap will keep softening up with wear.

Bought this for my dad's 75th
Got the Silver Black edition for my dad's birthday in Colorado. He likes classic black-dial field and pilot watches on leather, and he loved the small-seconds sub-register right away.

Clean black dial and smooth small-seconds hand. Fits my wrist well.

Surprised by the Movement and Case
Getting a Japanese 9020 automatic with a sapphire crystal and sapphire bezel at $220 made me skeptical at first. Once I put it on my wrist, the solid 316L steel finishing and weight convinced me immediately.

Solid Specs
Case measures right at 42mm with clean brushing on the 316L steel flanks and a flush black sapphire bezel. The Japanese 9020 automatic holds within a few seconds a day and legibility against the matte obsidian dial is strong.

Great Birthday Gift for My Husband
Bought the Silver Black Polaris 1790 for my husband's birthday. He is super picky about automatic watches, and he wears this to the office almost daily. His only comment was the small-seconds subdial numerals are a little small without his reading glasses.

Happy birthday to your husband, Danielle! Glad the Silver Black 1790 passed his test, and we appreciate the note on the subdial markings.
