While browsing the internet, I discovered this Omega vintage Chronograph that I'd never seen before.

Not only does it have beautiful angular lugs, but it's also powered by the caliber 321 or its ancestor.

Here are four examples.


EXAMPLE NO. 1

34 mm pink gold case. Manufactured in 1947-1948







The watch is presented as "equipped with the 27 caliber, ancestor of the 321"




credit: Jean-Marc Botazzi 


EXAMPLE NO. 2

35 x 45 mm yellow gold case from 1947

The watch is presented as ref. 2550

















The caliber is presented as Cal. 321 based on Lemania 27Ch C12

EXAMPLE NO. 3

35 mm yellow gold case. Year 1947

About the Omega Chronograph Ref. 175.0032

This Omega chronograph represents the brand's sophisticated approach to multi-function timekeeping during the mid-to-late 20th century. Omega's chronograph heritage runs deep, with the company producing timing instruments for professional sports and space exploration. The angular lugs visible in this example demonstrate the design evolution from earlier rounded cases, reflecting the geometric aesthetics that gained prominence in luxury watchmaking during this era.

The white dial configuration features the classic tri-compax layout with subsidiary dials at 3, 6, and 9 o'clock, complemented by a tachymeter scale on the outer perimeter. This arrangement provides chronograph seconds, running seconds, and what appears to be a 30-minute counter, delivering the essential functionality expected from a serious timing instrument. The gold case construction and applied hour markers suggest this was positioned as a premium offering within Omega's chronograph lineup, balancing sports functionality with dress watch refinement.

Vintage Omega chronographs with distinctive case architecture like these angular lugs have developed a dedicated following among collectors who appreciate the brand's design experimentation beyond the more commonly seen Speedmaster Professional. The combination of precious metal construction and chronograph complication places this piece in the upper echelon of collectible Omega timepieces, particularly when found in well-preserved condition with original components intact.

I thought (think) some of us might find the lugs too angular and disgraceful 🤷🏽‍♂️

Amazing reference, quattro!

These 34mm Omegas with the 321 are amazing on the wrist. I've got a steel pretty beat up Seamaster on a bracelet that I bring out in the summer, but it's not as luxurious as these. That first one with the patina and the buckle -- oh la la...
