Because of their large size and military heritage, Panerai watches aren't something that would naturally appeal to me.
But I've seen a lot of enthusiasm for them on this site, so I decided to go and see them in person.
After being given a very interesting presentation of the brand's history, I asked to try on the two models that attracted me the most, both with wire lugs.
RADIOMIR TRE GIORNI, ref. PAM01350
First observation: though big, the
45 x
14.15 mm
cushion case is
surprisingly “
wearable”, even on my 16 cm wrist.

The “
dégradé beige”
dial looks very
nice (and it matched my sweater).

The
cushion case with
wire lugs and
cone-shaped crown is really
appealing, especially in this AISI 316L
Patina steel, which gives it a gentle
vintage vibe.

The only things I have
mixed feelings about are the
sandwich dial and the
2-section pencil hour hand:
- I think I would prefer a single-layer dial.
- And, even if I like the double pencil shape of the hands, I think I would prefer the hour hand to feature only one section, like the minute hand.

The
case profile is
wonderful: I love the
curvature of both
top and
bottom surfaces tightening towards the
soft corners and giving the case its “
inflated” or “
pillow‑like”
volume.

The other model which caught my eye was the...
RADIOMIR CALIFORNIA 8 GIORNI, ref. PAM01349
Size wise, the case is almost identical: because of the sapphire case back, it is 14.25 mm thick instead of 14.15 mm, but one can't feel the difference.

There's a
lot to
love about the
dial:
- The iconic “Error-proof” (nicknamed “California”) design, which mixes Roman and Arabic numerals is very much to my taste.
- And so is the absence of any brand name (such a pleasure, really).
- And I prefer this single-layer dial with painted luminescent railroad track and hour markers.
The dégradé green color is nice too, even if it emphasises the military heritage of the watch, which isn't really my personal thing.

The “
burnished”, PVD coated (
Brunito), steel
case looks nice, but I think I
prefer the
more natural look of the
Tre Giorni.
And I really
dislike the
branded strap (“G. PANERAI & FIGLIO”): they removed the brand name from the dial only to put it on the strap, what a
shame!

The
case profile is
identical to the
Tre Giorni and it really is one of the things I like the most about these watches.

Just for comparison, I also tried a
40 mm model, a
Radiomir ref.
PAM01572, but it
didn't appeal to me at all.
Even if the size was friendlier to my wrist, it looked
strangely dressy and, with the
small seconds and
date,
lacked the
simplicity of the two other models.

If I had to
choose between these
two models, I would have a
hard time making up my mind.

As I said to the sales person,
ideally I would like to have the
Tre Giorni case and
strap with the “
Error-proof”
dial of the California.

But since such a model doesn't exist, I think I would probably
ultimately opt for the
Tre Giorni because I find the
color scheme (and the price) more friendly and because...

...it features a
solid case back and a
3-day movement (P6000).
I love that both watches feature a hand-wound movement with a wonderful screw-down crown to wind them, but I don't really see the purpose of an 8-day movement here (P5000), nor of a display caseback.
That said, both watches are really appealing and I could continue to hesitate for quite some time.
Thanks for reading.
Best, Emmanuel
