Some more Helvetia advertising from about 1930 which has a fold up bottom strip which holds an insert with illustrations of the watches.
As well as the brilliant advertising hype it's interesting to me as it shows the model numbers and also the fact that they seemed to make these in silver and chrome and two different mens' sizes as well as a ladies size. I've only ever seen silver 30mm or so versions.
I've added a google translate version of the text underneath.
HELVETIA
WATERPROOF WRISTWATCH WITH SHOCK ABSORBER
On sale at good watchmakers
Take away all the trouble by buying a HELVETIA waterproof wristwatch
Remember that this watch is also equipped with a shock absorber, an ingenious mechanism that prevents the balance shaft from breaking in 80% of cases, and you won't be able to repress a feeling of admiration.
By taking care of your HELVETIA watch which is waterproof and shockproof, you will find that the risk of breakage is practically eliminated, that repairs become very rare and that you can be sure of the accuracy of your watch. This will serve you well for many years.
The precision of a watch is also largely due to the purity of the oil used, because the balance performs
5 oscillations per second, i.e. 432,000 per day, and 157,680,000 per year,
without ever stopping, the pivots must roll in a very fine oil.
A waterproof case will preserve the purity of this oil for a very long time, because neither dust, nor humidity, nor other oxidizing agents, such as perspiration, can penetrate it.
The many advantages of the HELVETIA waterproof watch with shock absorber make it the ideal watch for all uses and in all climates.
