Is any one familiar with the copy Venus 75 Working Chrono Manual Handwind Movement! I noticed this movement was fitted in the PAM308 (Luminor Regatta Yacht Challenge) on a couple of dealers websites. How does this movement compare to the A7750 movement for example.

Seagull ST-19 is the name of the movement [NOT Lemania or Venus like some dealers call it], "bulletproof" as they say, VERY reliable. The A7750 has no comparison to the ST-19. Take note the ST-19 works at 21,600bph NOT 28,800BPH like the high beat A7750.

P.S.

You posted in the wrong section of the forum. :?

Yep, known to be quite reliable. I'd say moreso than the A7750.

I moved the topic for you, BTW.

Seagull ST-19 as mentioned. By far the best movement available in a replica as far as a working chronograph or otherwise, IMO.

Here's a fun fact, the ST-19 is not a copy of the Venus 175 per se... it technically IS the Venus 175 because they bought the tooling to make the Venus 175 in the early 60's. There are two main differences between the ST-19 and the Venus 175... the incabloc style shock absorber and the beat rate, which was increased from 18,000BPH to 21,600BPH.


The movement comes in 6 variants:

ST1901
2 register,
small seconds at 9,
30 min counter at 3
(Ex Venus 175 - parts compatible, Venus parts can be used for repair)

ST1902
3 register,
small seconds at 9,
30 min counter at 3
12 h register at 6 (non chrono!),
The 12h register's hand is directly geared to the main hour hand - bloody useless. See the pictures of the "Schaferwatches" 3-register chrono, the 12h in the register is always in the same position as the main hour hand.

ST1903
3 register,
small seconds at 9,
30 min counter at 3
24 h register at 6 (non chrono again),
The 24h indicator is directly synchronized with main hour hand, either used as 24h indicator or with the hand replaced by a day/night disk as a faux moon phase - day night indicator.


New variants 2007

ST1905
2 register,
small seconds at 9,
30 min counter at 3
de-central power reserve at 4:30
(Plazeon chronos)

ST1907
2 register,
small seconds at 9,
30 min counter at 3
central power reserve indicator

ST1908
4 register,
small seconds at 9,
30 min counter at 3
date at 12
day/night window at 6

No info about the "missing" denominations ST1904 and ST 1906.

Seagull is developing or considering:
A true 3-register chrono with a 12h chronograph counter at 6, prototypes have been built, this might be one of the missing denominations.
A GMT variant of the ST1903, where the 24h register can be set independently - only in consideration.
The addition of an automatic winding mechanism to this movement (allegedly prototype status).

I love informative posts like this one. Gracias guanaco!

By the way, one of the reasons I love this movement is due to the fact it has a colum wheel. WIS consider column wheel chronos much better movements than their counterparts (can't remember the exact term for the part :? )

Cheers!

Thanks Guanaco, I did not know this either! I woke up, drinking my fav-expresso and am immediately more knowledgeable about this crazy hobby and one of my fav-movements! :D

Cheers!

Very interesting information.

To add to that, there is also a fully working moonphase (not day/night) version.
I dont know what it is called, but I have a Zenith El Primero where it works perfectly :

This movement seems to be available in a number of other reps.

This would be great!
I would love to see this on something like the Omega Moon-watch. Would it be an accurate clone? No, However, it would be incredibly useful and provide a feature not available in the original.

This is one of the best movements available in replicas if not the best one.
Perfect for reliable chronos
Bear in mind it is low beat and manual winding

BTW awesome post by guanaco . Thanks for it

Another piece of information that may help determine how nice the movement is. I have a speedmaster rep that has the ST1902 manual wind, and I replaced it because I dropped it and broke one of the chrono wheels. The movement sells from CousinsUK for $138 USD. As a comparison, the Seiko 7s26 found in the common "Black Monster" or SKX007 is only around $85. The 007 and black monsters sell for around $200. The speedmaster rep sells for only $238 or $250. So for $50 more than a Seiko, you get a much better movement. My watch maker was really impressed by this movement, and so far it is "bullet proof"!
