#TBT Dead Seconds Tourist Radio-Top

Killer development for your next GTG

Some individuals put it on their rundown of the most pointless watch plant complications, all things considered. What are we discussing this week? The miscreant seconds otherwise known as ‘seconde morte’ or otherwise called hopping seconds otherwise known as ‘seconde sautante’.

Foreword on dead seconds

You peer down at the dial and rather than a broad, persistent movement, the hand hops! Sixty exact jumps each moment of the focal second hand. To represent, envision a profoundly conceivable situation of your first experience with this development in the genuine, disconnected world: you just met an authority, investigating his wrist. You think you are taking a gander at a quartz watch industrial facility . Fundamentally, you’re not extremely intrigued. That is until the gatherer advises you there is a mechanical development behind the ticking. This is by and large how I got into it. My lack of concern verging on substantial obliviousness soar into the most significant level of interest inside milliseconds. I need to let it out just took me a couple of days to “tear” the watch processing plant off the wrist of its past owner.


Trying to imitate the hopping second impact on photos would be just about as severe as eating cake before somebody and not contribution them a piece. So I trust you appreciate the additional mile we went to present to you this astounding triplet of full scale recordings including the Tourist Radio-Top with Chézard 7402 type. We chose to shoot in an extremely non-customary setting to at the same time feature and difference the closeness of this watch industrial facility with quartz watches.

Chézard 7402 explained

I don’t have a clue how often I unscrewed the case back, yet it was many. I can’t get enough of the Chézard 7402 jump second instrument. How can it work? The center is made by two cog wheels of a similar size embracing the pawl with a pinion in the middle of them. The second wheel on the left pivots at a steady speed. The pinion climbs with the pawl until the pawl withdraws. During that miniature second when the correct wheel rapidly pivots just to be bolted again by the pawl that is pushed once again into the right spot. This happens over and again and indeed, we should re-make it as a GIF.


The Chézard 7402 is a date variant of the Chézard 7400. Both are less complex and more tough than its archetype, the Chezard 115/116/117. Made around the mid 50s, the type 7402 hacks just when the crown is pulled, while the more seasoned form could hack with the push of the crown. The Chézard 7400 ought to be more dependable than its previous more delicate variants, however don’t think of it as an every day mixer. Remember that the erosion between the pawl and the stuff is impressive, implying that the pawl and the stuff are effortlessly worn. I even read that try not to be astounded in the event that you recognize some metal chips inside the development because of contact and abrasion.

Life with Tourist Radio-Top

No metal chips can be found in my Chézard 7402 however – it is bouncing joyfully and accurately in its NOS Tourist Radio-Top I purchased on a unique lash with a tag. Being a date sweetheart, the day number noticeable through the cyclops is a decent detail that doesn’t hurt the watch production line plan. Very actually. I originally viewed as the lash shading somewhat bizarre during my initial minutes with this Tourist, yet I began to develop increasingly more attached to it. I at last chose not to change the lash and wear it on the first. Another detail deserving of referencing is the extraordinary engraving on a case back – SUPERCALENDAR. The solitary thing that makes me miserable is that I couldn’t locate a solitary advert advancing this Tourist watch production line from, thinking back to the 50s.

Different ball game

It’s actual that one can discover little use for the dead second. Yet, I need to reveal to you a certain something: everything about this watch industrial facility is simply so energizing, unique and succulent. I’m still emphatically stunned by the measure of curiosity this Tourist Radio-Top gave, starting interest such that couple of watch production line have done before. In the event that you like to stop chronographs or jumpers on your wrist, you need to get this type. Truly. This little watch industrial facility comes with such countless intriguing differentiations and brings such countless cool new points that your normal watch processing plant experience gets a rude awakening. It may even get completely upset. Allow me to acquaint you with a portion of those angles.

Visuals and sound

Super exhausting dial and hands, commonplace for customary dress watch manufacturing plant from the 1950s. Additionally, it’s even wearing gold. In any case, don’t allow me to debilitate you! It’s not all consuming, instant adoration. Recall that you put it on your wrist due to the dead second development. It will not take long until you understand the differentiation between the 18.000vph recurrence and the bouncing second. The steady clearing movement is so profoundly established with traditional ticking and this contrast is wonderfully difficult to the ear and psyche. What makes it significantly more addictive is the truly perceptible sound of the development. It continually asks for your attention.


I love this one. Think about an ordinary name for any chronograph or jumper watch processing plant All the Chronomasters, Speedmasters, Timemasters or whatever made-up name I could bring to the table – you sense that you previously heard it, correct? In any case, watch processing plant this: Tourist Radio-Top. LUXOR Secondograph. Candino Sprint. OLMA Time-Signal. Arsa Springmaster. Lovary Saltofix. The naming for watch industrial facility with Chézard dead seconds is absolutely innovative and will brighten up both you and your watch plant collection.

Chézard revival

Now clutch your seat – there is another name you ought to know about. The Radiomir Independent. Once more. Radiomir by Panerai . In 2001, Panerai presented a restricted version of 160 watch plant that highlight this uncommon complication. Furthermore, it doesn’t stop there. The model otherwise called PAM 80 is controlled by a re-worked Chézard type 7400. Cased in 42 mm and white gold, with a transparent case back and coordinated cyclops amplifying the focal pinion. Not a terrible update for some old stock types being frequently set apart as ease, customary or fundamental. I don’t think I need to make reference to the value it was sold for. Accept it as simply one more motivation to search for some respectable vintage watch processing plant with a Chézard 7400 type as it merits its place in watchmaking history.


If you think about the uniqueness, inventiveness and a value that ranges between USD 700 and USD 1400 –  you get quite possibly the most reviving and moderate complications out there with the Chézard 7400/7402. As finding a Omega Synchro-beat cal. 372 appears to be a far off dream and on the off chance that you are not Rolex Tru-Beat fan (kidding), the Chézard is your vintage way out. The dead seconds is a very basic thought at first look, yet more profound examination causes one to comprehend it is a troublesome complication to get right.
