Watch Battery Replacement
The most common job we do. We fit the correct cell, replace the case gasket and reseal, then pressure check where the case allows.
Quoted at intake
Most watch repair searches in New Jersey end up being one of eight jobs. Here they are, with what each one involves and roughly how long it takes. The most common of them has a page of its own, covering what a watch battery replacement actually involves and why the gasket matters more than the cell.

Quoted at intakeBracelet sized on your wrist, not estimated. We keep the removed links labeled with your name in case the watch changes hands or your wrist does.
Quoted at intakeLeather, NATO, rubber or steel, fitted and sized properly with the right spring bars so it does not drop off a cuff two weeks later.
Quoted at intakeScratched or cracked glass replaced with mineral or sapphire to suit the piece, with the bezel and gasket refitted rather than forced back on.
3 to 7 daysA crown that pulls out, spins without setting or no longer winds. Usually a stem or tube problem and usually fixable without touching the movement.
3 to 7 daysDeployant clasps that spring open on their own are the most common cause of a dropped watch. We repair or replace in matching metal.
3 to 7 daysA full strip, clean, oil and regulate for a watch running fast, slow or stopping. Coordinated through the specialist watchmakers we have worked with for years.
Quoted at intakeBrushed and polished surfaces restored separately so the case keeps its original lines. We will advise against it on collectible pieces where patina matters.
3 to 7 daysAny brand, any origin, any condition. If a piece is better off going back to its manufacturer, we will tell you that instead of taking the job.
We also service Cartier, Tissot, Citizen, Hamilton, Bulova and most Swiss and Japanese makes, plus unbranded and inherited pieces.
Astra Jewelers is an independent jeweler. We are not an authorized dealer or authorized service center for any of the brands listed above and are not affiliated with or endorsed by them. Brand names appear here only to describe the watches we accept for repair. Servicing that requires factory parts or factory certification is coordinated through specialist watchmakers or referred to the manufacturer when that is genuinely the better outcome for the watch.
Walk into the Upper Montclair studio during opening hours or WhatsApp a photo first if you want a rough idea before driving across New Jersey.
We look at the piece, tell you what it needs and give you a price. If the repair costs more than the watch is worth, we say so.
Every piece gets a realistic date at intake. We call you when it is ready.
A quartz watch from a department store can cost more to service than to replace. An inherited piece almost never is. We will tell you which one you have brought us before you spend anything, because a customer who trusts the answer comes back with the watch that matters.
Not sure whether yours is due? Our guide on how often a watch should be serviced covers the symptoms that actually mean it needs attention, and the ones that look like faults and are not. If a case has been opened before, our guide to what a water resistance rating actually means explains what resealing restores and what it does not, and the battery replacement page covers how the seal is rebuilt when a back comes off. And if you are shopping rather than repairing, Astra is the only certified Briston dealer in New Jersey.
Astra Jewelers at 250 Bellevue Ave, 2nd Floor, Montclair, NJ 07043 replaces watch batteries for walk in customers, Monday to Saturday, 10:00am to 6:00pm. We test the gasket and reseal the caseback rather than just swapping the cell.
Bring it to the Upper Montclair studio and we will size the bracelet on your wrist rather than guessing. We keep the removed links with your details in case you need them back later.
Estimates are free, made in person and always given before any work starts. A price over the phone or by email would be a guess, because most watches need the case opened before the real condition shows. Battery replacement and link removal sit at the low end, while crystal replacement, crown and stem work or a full movement service are quoted per piece once we have seen the watch. You approve the price before we begin.
We take in most Swiss and Japanese brands including Rolex, Omega, TAG Heuer, Breitling, Cartier, Longines, Tissot, Seiko, Citizen and Movado. Astra Jewelers is an independent jeweler and is not an authorized dealer or authorized service center for those brands. Complex movement work is coordinated through specialist watchmakers we have used for years. We tell you upfront when a piece is better sent to the manufacturer instead.
Battery changes, link removal and strap fitting are the quickest jobs. Crystal replacement and clasp work typically run three to seven days. A full movement service sent to a specialist takes longer. You get a realistic date at intake rather than an optimistic one.
No, walk ins are welcome during opening hours. Booking ahead means someone is free to look at your piece the moment you arrive.
After a battery change or caseback opening we fit a fresh gasket and reseal the case. Note that resealing restores the seal rather than certifying a depth rating, so we will tell you honestly whether a piece should still be trusted in water.
Yes. These are the ones worth bringing in rather than posting off. We look at the piece with you, explain what is realistic and say plainly when a repair would cost more than the watch is worth or when originality is better left alone.
On a mechanical watch the most common culprit is magnetism. A steel hairspring that has sat near a phone speaker, a laptop or a magnetic bag clasp starts running noticeably fast. Demagnetizing it is a quick bench job rather than a full service. If the watch still misbehaves after that, it needs a proper look. On a quartz watch, losing time usually means the battery is dying. A battery change settles the question cheaply before anyone talks about the movement.
No. A smartwatch seals a rechargeable cell behind an adhesive-bonded screen and pairs it with the software, so that work belongs with the manufacturer. We would rather say so than experiment on your watch. What we replace are the silver oxide button cells in quartz watches, which is a different job done with a case tool and a fresh gasket rather than a heat plate.
