A cool Japanese automatic is a great gift for a teenager. I have three half-siblings, my dad's kids. When the oldest had his first Communion, me and my dad got him a Seiko SNK809. He's got an active lifestyle, so it seemed most appropriate to give him a sporty watch.

In a way, your son reminds me a bit of myself, when I was his age. As a kid I've been obsessed with fountain pens. When I was 14 or thereabouts, I saved up for - and bought - a Waterman Hemisphere. Rather basic compared to your son's Duofold, but at the time it was my treasure and pride. I also looked up to my dad in style, so I've been the only kid around wearing button-up shirts and blazers...alternating between these and a leather jacket over a Guns'n'Roses T-shirt.

The dial has been badly repainted. Ghastly relume job is just one flaw. The Omega font is all wrong, the minute track is quite dreadful as well.

As I've said, even with an Omega mainspring and crystal, the cost of servicing shouldn't be that high. The gaskets don't need to be ordered from Omega, they're just rubber O-rings without any structural peculiarities.

Omegas with bumper auto movements (3XX series) and some rotor automatics (49X and 50X series) can generate high servicing costs, because parts of the automatic winding works tend to be worn in them, and spares are hard to come by. But the parts you've been told need to be replaced are nowhere near generating a bill that high. Omega factory service could possibly quote you something like $1K.

However, the way I see it, in this case the only Omega-made part that's needed is the mainspring. And even that costs well below $100.

So, that estimate is basically the guy taking you for a 2-grand ride.

Hands were definitely replaced. While the seconds hand could be original, this is a no-lume dial, and it shouldn't have lumed hands. With that dial, Doxa used feuille (leaf) hands.

$2K for a service? No bloody way. The mainspring might cost a bit, but that alone will add a few dozen bucks to the bill, not a few hundred. As for the crystal, this case most likely takes just about any crystal, as long as it's the right size. $10-$20. If it was a Unishell case, like in a Seamaster De Ville, that could require an Omega crystal intended for a particular case, but even in these, some generic ones will fit - it's a pain to find one that does, but it's possible. Yours is not a Unishell.

Gaskets also won't add much to the bill. An ordinary watertight case like that takes two - one on the case back, one in the crown. Generic gaskets come in so many shapes and sizes that watchmakers buy large quantities of them, and there usually will be something that'll fit.

I didn't count, but then again, I didn't need to. It's these three...

They do use the G10 series. However, one movement can have many grades of performance and/or finishing. Are the Precidrive movements in Certina the same thing you'll find in the Moonswatch? Nope.

As for serviceability of quartz, you have to consider that in case of all that electronic stuff most manufacturers don't actually service them in the sense of dismantling the movement and replacing individual parts. The brutal truth is that most brands, be it TAG or Certina, tend to "service" quartz by their authorized service centres or factory service replacing the movement. That's even the case with Omega. How do I know TAG does that? Because in the course of handling warranty cases in watch retail, I handled the documents concerning the work done on quartz watches by a TAG Heuer ASC.

If it has printed circuits, it's more likely to be replaced than serviced. Premium/high-end quartz like Grand Seiko is what gets serviced. Or vintage quartz/tuning fork movements that just cannot be replaced. Most watchmakers also won't bother, ones specializing in actually repairing quartz aren't common.
