Thanks. Yes mine is still equipped with engine-tutned bezel. Cheers

1501 is a great watch from what many would feel is the golden era of Rolex design. Happy New Year, and Welcome!

Welcome to the greatest watch forum on the net.

[eatt_river]

Thank you all again for warm welcome.
Noob question: is 1.4M serial ranges means an early seventies watch. If so, "IV-65" engraving on caseback inner is not production date "fourth quarter 1965"? Please enlighten me.

Def not early 70s. More like ‘66-‘67

Check out this chart here. It’s pretty accurate, given how not-exact dating is

That serial number can be consistent with that case-back. See @springer's great thread.

My 5513 case back is III65, and serial is 1.28M. IMO, yours probably match.

Welcome.

As the guys posted above, the chart I use, puts 1.4m at 1966/67.

[eatt_river]

Thanks all
So my example, an 1501 ref with 1.4M serial equiped with an 1570 caliber (hacking feature) is more consistent with an end-60s piece.
I am more relieved.

Hacking? Are you absolutely sure? I have been keeping records on the non-hacking/hacking transition, and it seems to be in the 2.5M-2.9M range. A hacking movement in a 1.4M case would be an extreme outlier.

And no, a 1.4M serial is NOT consistent with a late 60s piece. It is consistent with a 66 case-back code and production year. Please take a moment to study the charts that were linked above.

You keep asking questions about the originality of your watch, do you have some reason to be skeptical about it?

Yes, my 1570 caliber (D099035 serial engraved on movement outter ring) does have hacking second feature. As per Dr Ranfft datebase, those 1570 should have that feature.
Serial (IV-65) on caseback/model ref on my watch head are not spot on with chart you shared but roughly consistent.

I sumerize these serials:
Case at 12h: 1501 engraved
Case at 6h 1.400.4xx serial
Caseback inner: 2 engravings "1501" and below it "VI 65"
Movement 1570 serial "D 099xx".

Interesting. Im with Dan on this. Your watch should be Non-hacking. Could you pls share your source's website or database? Im curious to know what he has a cut off.

The cal 1570 entry in Ranfft's database simply says hack feature, it doesn't distuinguish between non-hacking and hacking versions. So clearly it's not entirely comprehensive.

Ah, got it. Thanks.

[eatt_river]

Dan. As to genuineness of my watch I count on you guys TRFers with more knowledge to ascertain. To me the piece is pleasant, consistently aged, works great. Event on the crystal edge in acrylic its bevel shines like a mineral sapphire crystal. Am happy with it even though it could be non genuine. I will post more pics when I reach post count requirement.

Honestly, I have no doubt that it is genuine. Even if there are replacement parts, there is nothing wrong with that. I only mentioned the hacking issue because you repeatedly asked questions about the consistency of the parts and numbers.

Thank you Dan for sharing you thought and even patience with me as always (I think we already met on the net since late 2016 in the other forum WUSeek ...)
I am not native English speaking so I might not clearly say what I really meant... Sorry for that.

If I am somewhat interested in genuineness it is just for the purpose of knowledge enrichment for me. Honestly
I felt "uncomfortable" to abuse your time and patience.
And if I am not doing this to the community, but it is just me, I would like to chat again here is this great forum.
Cheers.

Merci beaucoup de la part d’un ancien prof de francais pour Vietnamiens


For now I didn’t detect any inconsistencies on my 1501yet!
Maybe this: why the hell on earth my case has definitely been refinished (see photo below) while dial conditions are really nice. It’s meant a dial swap? Please share your thoughts. Tks.

[swaini3]

I dont see the link between a case being refinished/polished and the dial.
