Intern bleek de schade relatief beperkt, maar wel cruciaal: een afgebroken tab van het balanswiel. Dit heeft directe impact op de oscillatie en maakt het uurwerk onbruikbaar zonder ingreep. Verder geen structurele schade aan tandwielen of chronograafmechanisme \u2014 een meevaller gezien de impact.<\/p>\n<p class=\"p1\"><b>\ud83e\udded Uitgevoerde werkzaamheden<br \/>\n<\/b><b><\/b>Volledige demontage van het uurwerk en inspectie op verborgen schade.<br \/>\nVervangen van het beschadigde balansonderdeel (kritisch voor de gang).<br \/>\nReiniging van alle componenten<br \/>\nHerassemblage en smering volgens specificaties van de ETA 7750.<br \/>\nControle en afstelling van de chronograaffuncties.<br \/>\nVisuele beoordeling van kastschade, zonder ingrijpende cosmetische restauratie.

De chronograaf start, stopt en reset correct en de gangreserve is opnieuw binnen specificatie. Dit horloge is cosmetisch en technisch volledig hersteld \u2014 een goed voorbeeld van hoe robuust een ETA 7750 kan zijn, mits de kritische componenten intact (of hersteld) zijn.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-medium wp-image-772\" src=\"https:\/\/www.othryswatches.nl\/wp-content\/uploads\/2026\/03\/IMG_FF49C96C-0754-41A9-ABF9-72721BE6A059-225x300.jpeg\" alt=\"Baume&amp; Mercier - ETA 7750\" width=\"225\" height=\"300\" \/> <img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-medium wp-image-771\" src=\"https:\/\/www.othryswatches.nl\/wp-content\/uploads\/2026\/03\/IMG_9777-225x300.jpeg\" alt=\"Baume&amp; Mercier - ETA 7750\" width=\"225\" height=\"300\" \/> <img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-medium wp-image-769\" src=\"https:\/\/www.othryswatches.nl\/wp-content\/uploads\/2026\/03\/92D0C44B-29DB-4295-8F7D-1E8C92826B90-300x241.jpg\" alt=\"Baume&amp; Mercier - ETA 7750\" width=\"300\" height=\"241\" \/><\/p>","protected":false},"excerpt":{"rendered":"<p>Baume &amp; Mercier Chronograaf \u2013 caliber ETA 7750 Herstel na valschade met impact op kast en balans \ud83d\udcf8 Over het horloge Deze chronograaf van Baume &amp; Mercier is uitgerust met het robuuste en veelgebruikte ETA 7750 uurwerk.
