Does [not wearing] expensive rings and watches fall under the Hadith:
مَنْ تَرَكَ اللِّبَاسِ تَوَاضُعًا لِلَّهِ وَهُوَ يَقْدِرُ عَلَيْهِ دَعَاهُ اللَّهُ يَوْمَ الْقِيَامَةِ عَلَى رُءُوسِ الْخَلاَئِقِ حَتَّى يُخَيِّرَهُ مِنْ أَىِّ حُلَلِ الإِيمَانِ شَاءَ يَلْبَسُهَا
Whoever leaves (valuable) dress out of humility to Allah while he is able to (afford it), Allah will call him before the heads of creation on the Day of Judgement so that he can chose whichever Hulal of faith he wishes to wear.
[Reported by Tirmidhi and graded Saheeh by al-Albani in Saheeh Tirmidhi no 2481]
Answer: “Yes, if they are very expensive and high in price. No doubt they [fall under] the likes [of this narration]”.
