Challenging but enchanting
Based on retro-style mechanical timepiece, LK501 features a precise pendulum mechanism which requires more attention and patience. But the sense of fufillment is also doubled. After fully wound up, it can keep working for 3~4 hours maximum, prolonging the building fun as much as you want.
- a gravity-swing pendulum with precise anchor escapement
- appealing outlook of mechanical engineering
- double fun of model building & brain teasing
- perfect gift for mechanical lovers or family & friends

4 heures de plaisir à monter ce mécanisme, mais après avoir remonté le ressort, la pendule n’a d’abord fonctionné que quelques minutes… J’ai d’abord essayé la mise de niveau avec les cales F7, j’ai gagné 10 minutes de fonctionnement. J’ai ensuite remonté le ressort à fond et enlevé le balancier pour “roder la mécanique” puis j’ai ciré la roue d’échappement ainsi que la fourche du balancier, réajusté les palier qui étaient un peu serrés ; la pendule fonctionne pendant 4 heures.
Bien sûr c’est une pendule en bois, mais quel plaisir de la voir fonctionner !

Bonjour
Un petit commentaire de France
J’ai adoré monter cette horloge en quelques heures, un vrai bonheur. Le rendu esthétique est vraiment super. Néanmoins après de nombreux réglages, impossible de faire fonctionner l’horloge plus de 2 minutes… j’espère avoir un retour de robotime pour m’indiquer le problème.

We got this as a gift, and assembled it a couple months ago. A family of four engineering types, we put it together fairly easily, though we had to think through a few steps. We enjoyed it. Once it was together and we saw how it wanted to work, I took the pendulum assembly back out, carefully sanded and waxed its active edges and the gear that it interacts with. I then sanded the edges of all the other gears between the coil spring and the pendulum and applied powdered graphite to the gear teeth faces with a cotton swab. We also fine-tuned the placement of some of the gears on their shafts to line up better. Now a full wind-up on the spring lasts about eight hours of operation, with fairly decent time keeping. But you have to get the friction down on the gears.

Not a kit for the beginner. Took many hours and a lot of care.
Finish project look quite nice.
Wish it would run longer, only down side

Mine works perfectly for a number of hours. It was fun building it and the instruction manual is very good. The only snag is that the spring is not long and strong enough and so the clock loses impulse after a few hours. Otherwise ok.

T5 piece is transparent and located in the bag, not on wooden sheets.
