Kaliber 321 produceret 1946 til 1960

[hannover_dk]

Mads Gjødesen Skrev:Meget spændende læsning og en information jeg ikke tror mange kender. Det giver jo cal. 321 speedmasteren endnu mere historie og endnu mere interessant set med samler øjne. Der må være fabrikeret mange værker eftersom lageret holdt i 8 år. Der findes trods alt mange Speedmasters cal. 321 ure endnu og sikkert lige så mange er afgået til de evige jagtmarker.

Jeg går stadig og drømmer om en LE Speedy i 57 stk. med cal. 321, straight lugs og BA hands Sådan et gad jeg godt eje. Men det ser nok aldrig dagens lys...

Ja det må være en del i 1960 eller måske over 59 og 60. Ialt 40.8000 i perioden 1940-1960 (og så regner han jo 27CH12 som er basis for den med - for ellers ville det være 1946 som det også fremgår af andre dele af korrespondancen med ham, men i kan jo få et cut and paste af hvad han svarede i det seneste mail som uddybning af meget af det andet han beskrev.
(det med at the indicated date refers to the date of shipment - skriver han for at forklare hvad Oct 1968 på certifikatet referede til)

Dear Mr Hannover,

We have indeed produced all movements of cal. 321 from 1940 until 1960 = total units: 40’800 – when “freezed”, then the movement number was already engraved on each movement plate.

Therefore, the movements were used as required until 1968 when the replacement calibre 861 was gradually introduced. In other words, we had delivered “old” cal. 321 watches at the same time of the “new” references having the new cal. 861. This explains why certain movement numbers were not in “ sequence”.

The only reason for a change of calibre was due to the fact that any repair of the cal. 321 was extremely time consuming – hence, the production of cal. 321 was stopped in 1960 and this calibre was used-up until the replacement cal. 861 was ready for manufacturing; a entire new concept of production had been made and the actual cal. 861 is much easier to repair, without having lost anything of its high chronograph quality.

The movement number cannot be delivered as a continuous sequence and might have been delivered without taking into consideration “when” they were produced. Basically, we never had a continuous numbering of the movements for cal. 321 – a “package” of numbers was then assigned to the production lane, without taking into consideration when they have been produced.

As a matter of policy, the indicated date is the date of shipment of the complete watch and not its production date.

Hope this is now clear for you !

Have a nice day
