PART 02 · SMARTWATCHES

Tinier screws.
Bigger jobs.

Apple Watch, Galaxy Watch, Garmin, Fitbit, Pixel Watch. Every part on these is smaller, more glued, more sensor-packed than a phone — but we’ve been opening them for years and the toolkit is on the bench. Screen, battery, sensors, buttons, every small part.

HEADS UP — APPLE WATCH

Apple deliberately makes the Watch hard to service — adhesive, paired sensors, and a tiny work area. Diagnostic and quote are free, and we’ll always tell you upfront what you’re looking at before any work begins.

Some smartwatch cases can’t be re-sealed to factory waterproof spec after opening — we’ll always tell you which yours is and you can choose.

WATCH QUESTIONS

Common questions, plain answers.

If your question isn't here, send us a quick message — we'll usually come back within a couple of hours.

Why won't you fit a cheaper battery?

Because cheap watch cells leak inside the case. We've opened too many movements destroyed by alkaline leakage from a $4 cell that 'saved' somebody $15 the year before. Sony, Maxell, Panasonic and Renata cost more because they don't do that. The right cell, every time.

Can you swap my Apple Watch battery?

Yes — Apple Watch battery starts at $99 (Series 4 onwards). Free diagnostic and quote up front. Note that any opened Apple Watch loses its original Apple-rated water-resistance.

Do you service mechanical / Rolex watches?

For Rolex, Omega, Cartier and other 'haute horlogerie' — battery and band only. Full movement servicing we'll refer you to a specialised watchmaker. Quartz models from those houses we'll handle in-house.

Do you do straps and bands too?

For traditional watches we don't carry a strap or bracelet inventory — bring your own and we'll fit it on the spot, free with any service. For smartwatches it's the opposite: we hold a large Apple Watch band range (sport, woven, leather and link bracelets), plus common Galaxy Watch and Garmin straps. Sizing for any band done while you wait.

How long does a solar capacitor take?

45 minutes on the bench. Genuine Panasonic or Maxell capacitor, installed and calibrated. Eco-Drive, Seiko Solar and Casio Tough Solar capacitors typically last 10–15 years before replacement is needed.

My Apple Watch screen is cracked — is it worth fixing?

Often it's not. Apple Watch screen replacements run anywhere from $199 to $600 depending on the model — older Series sit at the low end, Apple Watch Ultra and current-gen sit at the high end. A refurbished or new unit can land in the same range, so on older Watches the maths can tip the other way. We also can't guarantee restoring the original factory seal once the case has been opened. Bring it in or give us a call — we'll look at the exact model and damage and give you an honest answer on whether to repair, replace or trade it in.

My battery is swollen and lifting the screen — is that dangerous?

Yes — swollen cells are a fire risk. Don't keep wearing it, don't charge it, bring it in immediately. We handle swollen-battery jobs safely on the bench with proper containment. Free diagnostic; the replacement itself is a normal-priced job from $99.

from $20

Wrist game restored. From $20.

Battery swap, link removal, sizing — most done while you wait at DFO Uni Hill. Smartwatch screen, battery and crown repairs typically same-day.

Went in today to get a screen protector put on my phone by Jacob. Cheap, fast, works with my fingerprint flawlessly. Great customer service. He even custom cut the screen protector to fit my phones hard cover ( so it doesn't get pushed off edges or bubble up). Highly recommend this place, will be returning for my future mobile phone needs.

Jacob was fantastic. I had struggled for days going stark raving crazy trying to get ads off my phone and Jacob took them off in the blink of an eye. I highly recommend Casemonkey for any phone issues.

Fantastic and Professional Service at CaseMonkey Uni Hill ​I had a great experience at CaseMonkey in Uni Hill! The team there was absolutely fantastic. I went in because my phone's charger port was giving me trouble, and they were able to assist me right away. The repair was done incredibly promptly, and the guys working were very professional and knowledgeable. They had my phone fixed in no time, and it's working perfectly now. I really appreciate their quick and efficient service. Definitely a 5-star experience! Highly recommend them for any phone repair needs.
